Engineered Hydrogel Biomaterials for Regenerative Medicine Applications
Abstract

Engineered materials that integrate advances in polymer chemistry, nanotechnology, and biological sciences have the potential to create powerful medical therapies. Our group aims to engineer tissue regenerative therapies using water-containing polymer networks, called hydrogels, that can regulate cell behavior. Specifically, we have developed photocrosslinkable hybrid hydrogels that combine natural biomolecules with nanoparticles to regulate the chemical, biological, mechanical and electrical properties of gels. These functional scaffolds induce the differentiation of stem cells to desired cell types and direct the formation of vascularized heart or bone tissues. Since tissue function is highly dependent on architecture, we have also used microfabrication methods, such as microfluidics, photolithography, bioprinting, and molding, to regulate the architecture of these materials. We have employed these strategies to generate miniaturized tissue modules. To create tissue complexity, we have also developed directed assembly techniques to compile small tissue modules into larger constructs. It is anticipated that such approaches will lead to the development of next-generation regenerative therapeutics and biomedical devices.

White OLEDs for Displays and General Lighting

Tannas Lecture Series: A Joint CNSI and Engineering Seminar Hosted by Prof. Yang Yang(1)

Abstract

In 1993, we have developed white-light-emitting OLEDs for the first time. Since then, the performance of white OLEDs have been steadily improved and, today, they are considered to be the light source of the next generation. OLED displays based on white OLEDs have also been developed and large-size displays have been commercialized. Recently, high quantum efficiencies (QEs) can be obtained by using phosphorescent emitters such as iridium complexes. External QE of 25 to 30 percent was achieved for blue, green and red OLEDs, which correspond to the internal QE of nearly 100%. Device lifetime at high luminance levels, which is required for general lighting, has been significantly improved by using the multiphoton structure. By combining the above techniques, OLEDs can be extremely efficient and possess extremely long lifetime, even at high luminance level. In 2010, Lumiotec Inc. has started small-scale production of white OLED panels in Yonezawa, and luminaires using their panels have been commercialized.

In this talk, recent progress in white OLED will be discussed.

Refreshments will be served following the seminar (~4:45pm).

Using Electronic Coupling To Control Magnetic Properties at the Atomic Scale
Abstract

The drive to continue Moore’s Law by shrinking electrical components down to the ultimate limit has led to a great deal of interest in atomic and molecular-scale electronics, in which individual atoms and molecules can be used as circuit elements. More recent proposals also seek to exploit the magnetic properties of these nanoscale objects in new applications in information technology and spintronics. In typical device geometries, the magnetic element is coupled to electrical leads, and these interactions can strongly affect the properties of the quantum system.

Using scanning tunneling microscopy and spectroscopy, we study the effects of interactions between individual magnetic atoms and molecules that are separated from an underlying metallic surface by a thin-insulating layer of copper nitride (Cu2N). For Co atoms on large Cu2N islands, we find that exchange coupling of the spin to the metallic bath can result in Kondo screening as well as dramatically shifting the energy levels of the spin and modifying its effective magnetic anisotropy [1], the property that determines the stability of its spin orientation. By controlling the exchange coupling, we can tune both the Kondo screening of the systems as well as the anisotropy energy over a broad range of values. Furthermore, this system constitutes one of the few cases in which an open quantum system’s energy levels, rather than just its excited-state lifetimes, can be controllably and observably renormalized.

Department of Physics, University of Oxford
Camera, Lasers, Action: Exploring Gene Machines by Single-Molecule FRET Movies

Abstract

Single-molecule FRET microscopy is a versatile fluorescence technique that serves as a molecular ruler on nanoscale distances and distances changes within biomolecules. During the past 15 years, single-molecule FRET has uncovered substantial information about the dynamics of nucleic acids (DNA and RNA), as well as the mechanisms of nucleic acid processing by a large variety of protein machines (“gene machines”). Such studies are often based on direct, real-time observation of the dynamics of surface-immobilized individual molecules of nucleic acids or their complexes with proteins, and offer first views of intermediates undetectable by more conventional structural and biochemical methods.

However, single-molecule FRET is often limited to a single observable, namely the FRET efficiency between the donor and acceptor probes; as a result, one may need considerable information about a system to interpret FRET signals appropriately. In my talk, I will describe how the coupling of the FRET signal with additional fluorescence observables at the single-molecule level can be used to explore transient reaction intermediates and reaction paths. Specifically, I will discuss combinations of single-molecule FRET with alternating-laser excitation (ALEX), tethered fluorophore motion (TFM) and protein-induced fluorescence enhancement (PIFE). I will also describe applications of such FRET-based techniques in mechanistic studies of gene transcription by RNA polymerase in bacterial and viral systems, as well as studies of site-specific DNA recombination. Prospects of extending single-molecule FRET in vivo will also be discussed using E.coli as the model system. Since those methods are general, they should be widely applicable to many other gene machines.

Opto-Reversible Materials Inspired by Nature: New Light on the Nano-Bio Interface

Abstract

Developing new materials for two-way communication at the bio-interface represents an emerging interdisciplinary research challenge, and brain-machine interfaces in particular are very exciting, with recent breakthroughs achieved from various labs around the world towards various neurotransmitter sensing, signaling, and net brain process readout. At the heart of many of these collaborative interface attempts lies developing new materials which are compatible with biological tissue, and sensitive to fast and subtle signals, yet can also interface with traditional technologies for readout and interpretation. Some promising new directions in bio-materials for bio-surfaces have turned to natural materials and processes for inspiration, specifically in using light as opposed to electrical signals, and in using softer bio-compatible materials for implants in place of hard metal electrodes.

At McGill University, we are part of an interdisciplinary team of researchers that has designed soft sticky polymers based on molecular opto-switches as artificial mimics of the retinal photo-switch proteins that enable human vision, and thus a direct interface between neural cells and optical technologies. These ‘artificial vision’ molecules based on azobenzene structures respond physically when irradiated by changing shape, to permit visible to be converted directly and reversibly to mechanical work. When applied as bio-coatings, reversible changes in surface energy are also inducible as a result, for a variety of reversible surface switching applications via light, which we have demonstrated to be able to control and guide adjacent cells. Irradiation with light in the solar spectrum at sun-like intensities has also been shown to lead to a reversible photo-expansion of these materials and coatings, of up to a few percent, allowing the materials to function as photo-mechanical switches or light energy harvesters and actuator devices. Some simple macroscopic devices were fabricated with them that take mechanical advantage of this effect for larger scale motion driven by sunlight, such as bending, rolling, and ‘walking’, allowing them to function and light-powered ‘artificial muscles.'

Joyce Cutler Shaw
Art|Sci Exhibition Opening: "What Comes To Mind"

Joyce Cutler-Shaw is an artist of inter-media, although drawing is at the heart of her work. She considers drawing to be a primary language, a way of knowing, a mode of inquiry, and an act of empathy. She has exhibited internationally since 1972. Her current series, The Anatomy Lesson [1990–present] explores themes of survival, evolution and transformation. She proceeds from the point of view that we are of nature, and that human history is natural history. Her sources and inspiration come from the natural and medical sciences.

The Anatomy Lesson is an investigation of human identity and the evolving self from birth through death. To realize this independent, fine art project, Cutler-Shaw was honored to be the first visual artist, nationally, to have a medical school residency for a fine art project as Artist-In-Residence and Visiting Scholar at the School of Medicine at the University of California San Diego (1991-present). She has been investigating the history of anatomy as a visual history of body imaging and the life cycle: how we are seen and how we see ourselves. To this end she has been visiting and documenting great historical medical collections and museums in the United States and internationally, as well as monitoring new medical imaging technologies.

She is the recipient of several prestigious grants such as Creative Capital Foundation, Rockefeller Foundation/Bellagio International Center, New York State Council for the Arts, National Endowment for the Arts, New York Foundation for the Arts among others.

Joyce Cutler-Shaw’s works—public installations, drawings and artists books—are represented in both Museum and Library Special Collections, including the Albertina Museum in Vienna, New York’s Museum of Modern Art, The 42nd Street Library, the Klingspor Museum in Germany, the Teylers Museum in The Netherlands, the Herbert Johnson Museum at Cornell, the National Museum of Women in the Arts in Washington, DC, and the Wellcome Institute in London.

Event Title

Defect States in Colloidal Quantum Dots Studied with Low-Temperature Scanning Tunneling Microscopy

Abstract

Defect states within the bandgap of a colloidal quantum dot can significantly contribute to the overall quantum efficiency of the chromophore. The trap state may act as transient states that open nonradiative-transition channels of the excitonic state in the quantum dot. We have observed defect states in CdSe (CdSe/CdS) quantum dots using low-temperature scanning tunneling microscopy. We have mapped the spatial distribution of different defect states at various energy levels. We prove that a simulation based on the non-radiative transition via the trap state can cause the power law dependence of ‘on’ and ‘off’ probability as a function of time in a quantum dot light-emitting-diode. We suggest the ways to reduce the “blinking’ for better performance as an ideal chromophore.

Diary of Smells: Shards

Diary of Smells is an ongoing multi-sensorial interactive abd interdisciplinary project. The olfactory, a forgotten sense and yet a powerful connector to memory and emotions is a protagonist among other characters such as sound, projection, sculpture, photography, book-art, mostly in the shape of installations.

Diary of Smells: Shards (estilhaços) is a work in progress composed of an installation and an olfactory artist's book. From the shards of broken wine glasses emerges a memory smell of a forgotten moment. The smells are reconstructed from texts written by several collaborators. Images emerging from the inscribed words instigate the creation of ten numbered fragrances in collaboration with Givaudan do Brasil, a leading fragrance and flavor company. This collaborative and interactive project takes the shape of an olfactory artist’s book and an installation.

The artist’s book shown here at UCLA is a work in progress. It comprises various stages of smell production, photographs and sound design.

About the artist: Josely Carvalho, a Brazilian multi-media artist lives in New York and Rio de Janeiro. Over the past three decades, she has assembled a body of work in a wide range of media that gives eloquent voice to matters of memory, identity and social justice while consistently challenging the boundaries between artist and audience and between politics and art.

Her latest project, Diary of Smells includes olfactory and its connection to emotions and memory in her visual/sound installations. She approaches smell through the construction of original fragrances (i.e. smell of nest), sculpture installations, smell video, photography, artist’s book, residences & smell walks.

She is the recipient of several prestigious grants such as Creative Capital Foundation, Rockefeller Foundation/Bellagio International Center, New York State Council for the Arts, National Endowment for the Arts, New York Foundation for the Arts among others.

She has exhibited extensively internationally in several museums and cultural centers and has works in several public collections. She has received her BA from Washington University, School of Architecture, St. Louis, Mo. & she has taught at the School of Architecture, National University of Mexico & SUNY at Purchase. She was the founder and director of The Silkscreen Project, St. Mark’s Church in-the-Bowery in New York City.

Reactive Monolayers: Templates for Biomolecules and Interfaces for Technology
Abstract: Self-assembled monolayers have been the workhorse for nanotechnology since a few decades ago. They constitute an interface and “interphase” between a substrate and the “outside world.” Their functions are by far not only the basic types such as substrate protection, anchoring and tuning of hydrophilicity, but have progressed into ever increasing added value ranging from molecular recognition (e.g. for sensing), molecular construction, biomolecular orientation, electronic transport, signalling, etc.
Reactive monolayers, i.e. monolayers that have some reactive moiety at the headgroup that allows further functionalization, form a subclass that is extremely useful for molecular (nano)fabrication. The reactivity of such monolayers can be the same or drastically different (faster or slower) than of their solution analogs.
The current presentation focuses on examples that range from biomolecular templates to technological applications. The development of reactive platforms that signal attachment reactions occurring onto them is useful for biomolecular arrays. Examples will be shown of protein patterns, using a thiol-reactive platform [1]. Surface gradients are being developed and used to address and map reactivity profiles on surfaces on reactive monolayers [2]. Additionally, an example using paramagnetic complexes to make spintronic devices is shown [3]. Current and future developments of these lines will be shown as well.

Exploring molecular assembly at surfaces
The adsorption and self-assembly of organic molecules at surfaces has recently been investigated extensively, both because of the fundamental interest and for prospective applications in nanoelectronics. Molecule–molecule and molecule–substrate interactions can be tuned by appropriate choice of substrate material and symmetry. Upon molecular adsorption, surfaces typically do not behave as static templates, but often rearrange to accommodate different molecular species. We review recent experiments using Scanning Tunnelling Microscopy, providing new insight into fundamental properties such as molecular diffusion and self-assembly via surface templating and H-bonding driven by co-adsorption. Our approach is to modify surfaces providing suitable surface cues, that may guide the assembly of adsorbates. Recent advances in using the substrate as catalyst for surface confined polymerization reactions will also be discussed.

Mapping adhesion, cytoskeletal and signaling protein transport and interactions in living cells by image correlation spectroscopy
Abstract: Image correlation methods are an extension of fluorescence fluctuation spectroscopy that can measure protein-protein interactions and macromolecular transport properties from input fluorescence microscopy images of living cells. These approaches are based on space and time correlation analysis of fluctuations in fluorescence intensity within images recorded as a time series on a laser scanning or total internal reflection fluorescence (TIRF) microscope. We recently introduced spatio-temporal image correlation spectroscopy (STICS) which measures vectors of protein flux in cells based on the calculation of a spatial correlation function as a function of time from an image time series. Here we will describe the application of STICS and its two color extension, spatio-temporal image cross-correlation spectroscopy (STICCS), for measuring transport maps of adhesion related macromolecules such as integrin, alpha-actinin, paxillin, talin, and vinculin within, or associated with the basal membrane in living U2OS osteosarcoma and CHO cells as well as during dynamic turnover of podosomes in dendritic immune cells. We will also highlight recent advances we have made with a new form of reciprocal (k-) space ICS, called kICS, that allows us to measure unbiased transport coefficients of fluorescently labeled membrane proteins even if there is complex photophysics (such as nanoparticle emission blinking) of the probe. We will describe kICS measurements of the transport properties of quantum dot labeled GPI anchored proteins in the cell membrane. Finally we will show how an extension of kICS was used to measure the transport properties of Cystic fibrosis transmembrane conductance regulator (CFTR) and detect transiently confined and more freely diffusing populations of this ion channel in the cell membrane.

Innovative solutions for sustainable energy and personalized healthcare: A role for nanotechnology
Two of society's most urgent needs – our growing demand for energy in a world with finite reserve of fossil fuels and the need to improve patient quality of life at a cost we can afford – present opportunities for the nanotechnologist. Scientists working at the nanometer scale – one billionth of a meter – are increasingly fashioning custom materials with precisely designed properties. We are endowing matter with new light-absorbing, electron-harvesting, molecule-analyzing, and state-reporting properties that are programmed in at the time of chemical synthesis and materials fabrication.

We will present the latest breakthroughs in solar cell technologies: flexible photovoltaic devices, printed like newspapers, that make the best use of the sun's broad visible and infrared spectrum. We will also discuss progress towards rapid, point-of-care, low-cost molecular diagnostics technologies that enable the early and sensitive detection of disease, results that guide the physician towards more responsive and more effective treatment solutions.

The talk will include both the latest advances in the lab and a discussion of the commercialization of these technologies in the form of start-ups InVisage Technologies and Xagenic.

Art|Sci Exhibition: Christina Agapakis "Bacterial Encounters"

Microbes are often synonymous with rot, decay, infection, and disease. When microbes are made visible—or worse, smellable—it signals danger, a situation best avoided. But microbes are unavoidable, essential as part of the ecology of the healthy human body and the global dynamics of biogeochemical cycles. The growing realization of microbial usefulness and diversity is changing our relationship to microorganisms from one of fear, isolation, and sterilization, to a more ecological understanding of symbiotic exchange. Bacterial Encounters is an exploration of nature and culture from a microbiological perspective, capturing the microbial ecology and the living diversity thriving after the death of the Salton Sea. Through culturing such microbes, we make visible the ecologies that make up our world.

Delivering nanoparticles to cells: the challenge of exiting the endosome

Abstract: Nanoparticles, which range from metal and semiconductor nanocrystals to dendrimers, represent a potent assembly platform for decoration with proteins, peptides, nucleic acids, drugs, contrast agents and the like in pursuit of creating new nanomedicines and theranostic devices. At the most basic level these constructs will in many cases be required to undergo uptake into targeted cell populations to fulfill their intended role. The most popular method for facilitating nanoparticle uptake into cells is the use of cell penetrating peptides. Despite their diverse sequences and structures, these peptides invariably take advantage of some type of endosomal uptake to accomplish cellular delivery. Although somewhat efficient for delivery of noncovalently attached cargo such as nucleic acids to cellular targets outside the endosome, the nanoparticles themselves invariably remain sequestered in this complex vesicular system. The talk will focus on recent efforts with a modular, multifunctional peptide system to address and overcome this challenge. Preliminary screening of an initial peptide designed to deliver palmitoyl-protein thioesterase inhibitors to neurons indicated it could mediate endosomal escape of semiconductor quantum dots (QDs) in cultured cells. Detailed studies characterized properties relevant to the peptide’s ability to mediate cytosolic delivery of QDs to a wide range of cell-types, brain tissue culture and the developing neuronal system in a model chick embryo system in a remarkably non-toxic manner. An iterative structure-activity relationship analysis of the peptide undertaken by discretely modifying key components including length, charge, fatty acid content and their order allowed us to define key motifs required for endosomal escape, to select more efficient escape sequences, along with unexpectedly identifying a sequence that specifically targeted QDs to cellular membranes. A model of peptide function and implications for in vivo labeling and nanoparticle-mediated drug delivery will be discussed.

Silicon Nanostructures for Energy Applications

Featured Speaker: Prof. Shuit-Tong Lee, Director, Institute of Functional Nano & Soft Materials (FUNSOM); Dean, College of Nano Science and Technology, Soochow University; Director, SUN-WIN Joint Research Institute for Nanotechnology, Soochow University

Abstract: Si nanostructures in various forms can be controllably synthesized using metal-assisted vapor-liquid-solid growth, oxide-assisted growth, chemical or electrochemical etching methods. Si nanostructures (nanowires, quantum dots) exhibit unique and interesting structural, optical, electronic and chemical properties, which are being exploited for myriad exciting applications. For example, energy devices based on Si nanowire arrays can achieve efficiencies as high as 12% for solar energy conversion. Additionally, Si nanodots and nanowires can serve as efficient photo-catalysts for the redox reactions of organics. This presentation will discuss and highlight our recent works in developing silicon nanostructures for green, high-efficiency and low-cost solar energy harvesting and catalysis applications.

Towards In-vivo Foster Resonance Energy Transfer Imaging

Featured Speaker: Professor Xavier Intes, Associate Professor, Biomedical Engineering Department, Rensselaer Polytechnic Institute

Hosted by: Dr. Xavier Michalet & Prof. Shimon Weiss

Abstract: Fluorescence is a ubiquitous readout of molecular localization that has enabled the elucidation of many biological processes. Co-localization of different fluorophores via fluorescence microscopy allows one to monitor protein interactions, but this has been limited by the resolution of the imaging technique used. Although super-resolved imaging microscopy techniques can break the diffraction limit, imaging of protein interaction is not directly achievable, but can be sensed via Forster Resonance Energy Transfer (FRET). FRET is the radiationless transfer of energy from an excited donor fluorophore to an appropriate acceptor in close proximity. The energy transfer only occurs between fluorophores separated by less than ~10 nm, enabling sensing of protein interactions at the nanoscale. However, to date, FRET applications are confined to microscopy of cells in culture. It is becoming increasingly important to translate FRET assays to small animal imaging where the in vivo physiological context is critical for drug development, the study of diseases, and fundamental cellular and molecular biology.
I will present my laboratory’s efforts towards establishing whole-body FRET imaging in small animals. I will report current instrumental, theoretical and experimental efforts at Rensselaer Polytechnic Institute to develop a new method to perform whole-body fluorescence molecular tomography (FMT) based on wide-field time-resolved illumination. I will also summarize our efforts, in collaboration with Dr. Barroso laboratory at Albany Medical College, to characterize an adequate near-infrared FRET pair and its application to monitor NIR-FRET labeled- iron-binding transferrin protein internalization in cancerous cells based on the reduction of donor fluorophore lifetime.

Bio: Xavier Intes is an Associate Professor in the Biomedical Engineering Department at Rensselaer Polytechnic Institute, Troy, U.S.. Dr. Intes received his Ph.D. in physics from Université de Bretagne Occidentale, France. He was a postdoctoral fellow at the University of Pennsylvania under the mentorship of Britton Chance and Arjun Yodh. Dr. Intes was the Chief Scientist of Advanced Research Technologies Inc, Montreal, Canada, and oversaw the development of two commercial time-resolved tomographic optical imaging platforms: Optix® and SoftScan®. He has been a faculty member of the Rensselaer Polytechnic Institute since 2006.
Dr. Intes’ research interests are on the application of optical techniques for biomedical imaging in pre-clinical and clinical settings. His research concentration is on functional imaging of the breast and brain, fusion with other modalities, and fluorescence molecular imaging. The goal of his laboratory is to develop quantitative thick-tissue optical imaging platforms by focusing on three main areas: (a) design of new optical tomographic imaging instrumentation; (b) developing new reconstruction algorithms for quantitative volumetric imaging; and (c) investigating optimal experimental and theoretical parameters for functional, molecular, and dynamical optical imaging.

"Designing a Nanoviricide ® - Biophysics is the Key"

Featured Speaker: Anil R. Diwan, Ph.D., President and Chairman, NanoViricides, Inc.

Abstract: A "nanoviricide ®", is a biomimetic decoy designed to fool a virus particle into binding to it and thereby capturing the virus particle and rendering it harmless. It is constructed by chemically attaching virus-binding ligands to a polymeric micelle. Biophysics is of prime importance in designing these structures. The biomimetic ligands tend to have poor energies of interaction with the virus particle per ligand, yet a large number of ligands enable a successful interaction with the virus particle. Additionally, the nanoviricide competes with cells for binding to the virus particle, and must provide a substantially more efficient interaction than the cell-virus interaction, in order to achieve a therapeutic effect. The nanoviricide also must be able to exercise its effect in the biological matrix, be it in the bloodstream, plasma, mucosa, or other extracellular spaces. Further, it should have minimal undesirable interaction with the matrix and host cells so that sufficient material is available for clearing out a fulminant viral infection from a patient's body. In addition, the nanoviricide needs to be able to distribute itself within the body, across various barriers, so that it can reach the spaces where the virus particles are present. NanoViricides, Inc. has demonstrated that highly effective antiviral treatments can be created against a large number of viruses, despite these design challenges. The challenges and opportunities for understanding the behavior of virus-nanoviricide interactions, and the results from studies of nanoviricides development against various viruses such as influenza, HIV, Herpesvirus, adenoviruses, Dengue viruses, will be discussed.

Professor John Rogers, UIUC
Distinguished Materials Scientist Seminar

Materials for Bio-Integrated Electronics

Featured speaker: Professor John Rogers, Lee J. Flory Founder Chair in Engineering Innovation, Department of Materials Science and Engineering, University of Illinois at Urbana-Champaign

Abstract: Biology is curved, soft and elastic; silicon wafers are not. Semiconductor technologies that can bridge this gap in form and mechanics will create new opportunities in devices that adopt biologically inspired designs or require intimate integration with the human body. This talk describes the development of ideas for electronics that offer the performance of state-of-the-art, wafer-based systems but with the mechanical properties of a rubber band. We explain the underlying materials science and mechanics of these approaches, and illustrate their use in bio-integrated, ‘tissue-like’ electronics with unique capabilities in cardiac electrophysiology, brain-machine interfaces, and continuous health/wellness monitors. Demonstrations in humans and live animal models illustrate the functionality offered by these technologies, and suggest several clinically relevant applications.

Bio: Professor John A. Rogers obtained BA and BS degrees in chemistry and in physics from the University of Texas, Austin, in 1989. From MIT, he received SM degrees in physics and in chemistry in 1992 and the PhD degree in physical chemistry in 1995. From 1995 to 1997, Rogers was a Junior Fellow in the Harvard University Society of Fellows. He joined Bell Laboratories as a Member of Technical Staff in the Condensed Matter Physics Research Department in 1997, and served as Director of this department from the end of 2000 to 2002. He is now the Lee J. Flory-Founder Chair in Engineering at University of Illinois at Urbana/Champaign with a primary appointment in the Department of Materials Science and Engineering. Rogers’ research includes fundamental and applied aspects of materials and patterning techniques for unusual electronic and photonic devices, with an emphasis on bio-integrated and bio-inspired systems. He has published more than 350 papers and is inventor on more than 80 patents, more than 50 of which are licensed or in active use. Rogers is a Fellow of the IEEE, APS, MRS and AAAS, and he is a member of the National Academy of Engineering. His research has been recognized with many awards, including a MacArthur Fellowship in 2009 and the Lemelson-MIT Prize in 2011.

Klaus-Robert Muller
Technical University (TU) Berlin
Public Lecture Presented by the Institute for Pure and Applied Mathematics

Toward Brain Computer Interfacing

Abstract: Brain Computer Interfacing makes use of brain signals for the control of objects (e.g., wheel chairs), spelling, computer gaming, and other applications. This talk will provide a brief overview of current Brain Computer Interface technology. In particular, it will show the wealth, complexity and difficulties of the data available. The challenge is enormous: Neuro-electric activities provide a high dimensional, very strongly noise contaminated data stream. This data stream needs to be processed and decoded accurately and in real time, so that (metaphorically speaking) thoughts can be translated into actions.

The talk will then report in more detail about the Berlin Brain Computer Interface that is based on Electroencephalography (EEG) signals, and take the audience all the way through the processing chain. Finally, Brain Computer Interfacing application examples ranging from clinical studies where 'locked-in' patients achieve communication to non-clinical applications where, for instance, complex cognitive states while driving a car are analyzed, will be presented.

Speaker Bio: KLAUS-ROBERT MÜLLER is Professor of Computer Science at Technical University (TU) Berlin and Director of the Bernstein Focus on Neurotechnology Berlin. Since 2012, he also holds a Distinguished Professorship for Neurotechnology at Korea University, Seoul. He studied physics and obtained his PhD in Computer Science at TU Karlsruhe in 1992. Starting in 1995, he built up the Intelligent Data Analysis (IDA) group at GMD FIRST (later Fraunhofer FIRST) and served as department head until 2008.

Electricity- What's Next?

Renewables? Natural gas? Energy storage? At Carnegie Mellon’s Electricity Industry Center, we have been studying the characteristics of all these technologies to see how they might change the current electric grid. The discussion about renewable electricity has recently benefited from a scarce commodity: data. We now understand the character of fluctuations in power output from wind and solar power. Using the measured variations and moderate time resolution emissions data from natural gas generators, we can estimate additional air emissions from these generators caused by wind and solar. We know when connecting wind farms together with transmission lines to reduce variability reaches a point of diminishing returns, and are starting to learn how to best use new-technology batteries in the grid.

Crowdfunding for the Biosciences: A Real Prospect or Pipe Dream

Spurred by the passage of the Jobs Act, crowdfunding is the latest platform for companies and entrepreneurs to raise money. It is a way of raising capital that involves getting small amounts of money from a large number of investors. The Jobs Act has transformed the formerly "donate-to-my-cause" industry into a popular way for raising capital. This new source of money pushes behind some of the traditional sources like family and friends, angel investors and venture capital.

Crowdfunding promises to give some startups access to capital they wouldn’t have had otherwise, but it could also set up unprepared entrepreneurs for a headache. This SoCalBio mixer will provide a primer on this source of funding and discuss all the legal, accounting, and business strategy aspects of crowdsourcing for bioscience commercializatrion projects.

Our speakers and panelists will touch on:
  • How to crowdfund by reaching out to people in your network
  • How to tap into their desire to support your project and believe in your claims
  • How to keep crowdfunding legal
  • Are there crowdfunding best practices?
  • Is it realistic to crowdsource for biotech or medical device projects?
  • Will crowdsourcing hurt your chances of tapping into institutional money?

Greg Carman, Professor of Mechanical & Aerospace Engineering, UCLA
UCLA Science Faculty Research Colloquium

Future Nanoscale Multiferroic Devices

Present day electromagnetic devices rely on magnetic fields generated by passing a current through a conducting wire; a discovery made by Oersted nearly 200 years ago. While extremely useful, this approach fails at small length scales and thus presents a major obstacle to the further miniaturization of electronic devices. Recent scientific discoveries show that a magnetic material’s intrinsic magnetization can be manipulated with an electric field. This innovation thereby overcomes the deficiencies associated with Oersted’s current driven system, especially in the realm of nanotechnology. Professor Carman will describe the ongoing multiferroic research, and the potential applications that this new approach has to offer the scientific and engineering communities.

Speaker bio: Professor Greg P. Carman’s research is on understanding the multi-physics behavior of active materials such as piezoelectricity and magnetoelasticity. He is the Director of the new National Science Foundation Engineering Research Center focused on Translational Applications of Nanoscale Multiferroic Systems (TANMS), and is the Co-Executive Director of the Center for Advanced Surgical and Interventional Technology (CASIT) in the Department of Surgery at the University of California Los Angeles (UCLA).

Cyanobacteria as solar-powered biocatalysts that produce and excrete useful products

We have set out to “teach” cyanobacteria to use solar energy to fix CO2 to make and excrete organic molecules for human use, and not have the energy go into just biomass. We use the cyanobacterium Synechocystis sp. PCC 6803 as a model biocatalyst and focus on production of laurate, a saturated C12 fatty acid. In order to have Synechocystis produce laurate, we have equipped it with a thioesterase from plants that cleaves acyl-ACP (acyl-carrier protein), an intermediate in the native lipid biosynthesis pathway, when the acyl group has reached the C12 length. Modifications have been made in order to enhance carbon flux into the lipid/fatty acid biosynthesis pathway and eliminate laurate consumption by the cyanobacteria. Such new approaches to biofuel production can be much more sustainable and “green” than current practices, and makes cyanobacteria leading candidates for the production of the next generation of biofuels, commodity chemicals, and other compounds that currently are made from oil.

“Mott Memristors, Spiking Neuristors and Touring Complete Computing with an Action Potential”

Abstract:
Dr. Matthew Pickett and I have been collaborating on a project at HP Labs to explore the possibility of using "locally-active memristors" as the basis for extremely low-power computation utilizing neither transistors nor semiconductors but rather inorganic and electronic neurons. We first analyzed the thermally-induced first order phase transition from a Mott insulator to a highly conducting state in a family of correlated-electron transition-metal oxides, such as Ti4O7 and NbO2. The current-voltage characteristic of a simple cross-point device that has a thin film of such an oxide sandwiched between two metal electrodes displays a current-controlled or 'S'-type negative differential resistance (NDR) caused by Joule self-heating if the ambient temperature is below the metal-insulator transition (MIT). We derived simple analytical equations for the behavior these devices [1,2] that quantitatively reproduce their experimentally measured electrical characteristics with only one or two fitting parameters, and found that the resulting dynamical model was mathematically equivalent to the "memristive system" formulation of Leon Chua and Steve Kang [3]; we thus call these devices "Mott Memristors". Moreover, these devices display the property of "local activity"; because of the NDR, they are capable of injecting energy into a circuit (converting DC to AC electrical power) over a limited biasing range. We built and demonstrated Pearson-Anson oscillators based on a parallel circuit of one Mott memristor and one capacitor, and were able to quantitatively model the dynamical behavior of the circuit, including the subnanosecond and subpicoJoule memristor switching time and energy, using SPICE. We then built a neuristor, an active subcircuit originally proposed by Hewitt Crane [4] in 1960 without an experimental implementation, using two Mott memristors and two capacitors. The neuristor electronically emulates the Hodgkin-Huxley model of the axon action potential of a neuron, which has been recently shown by Chua et al. [5] to be a circuit with two parallel memristors, and we show experimental results that are quantitatively matched by SPICE simulations of the output bifurcation, signal gain and spiking behavior that are believed to be the basis for computation in biological systems. Finally, through SPICE, we demonstrate that spiking neuristors are capable of Boolean logic and Touring complete computation by designing and simulating the one dimensional cellular nonlinear network '137'.

Biography:
Stan Williams is an HP Senior Fellow and director of the Memristor Research group at HP Labs.

He is currently focused on developing technology that supports the concept of CeNSE: The Central Nervous System for the earth. The idea is that nanotechnology has the potential to revolutionize human interaction with the earth as profoundly as the Internet has revolutionized personal and business interaction.

Prompted by his exploration of the fundamental limits of information and computing, Williams recently completed extensive research in nano-electronics and nano-photonics.

For the past 30 years, his primary scientific research has been in the areas of solid-state chemistry and physics and their applications to technology. This evolved into the areas of nanostructures and chemically assembled materials, with an emphasis on the thermodynamics of size and shape.

Williams has been awarded more than 60 U.S. patents, published more than 300 papers in reviewed scientific journals and presented hundreds of invited plenary, keynote and named lectures at international scientific, technical and business events.

He has received numerous awards for business, scientific and academic achievement. Most recently he received the prestigious 2007 Glenn T. Seaborg Medal awarded by the UCLA Department of Chemistry and Biochemistry.

He was named to the inaugural Scientific American 50 Top Technology leaders in 2002 and then again in 2005 (the first to be so named twice). In 2005, Small Times magazine named the U.S. patent collection Williams has assembled at HP as the world’s top nanotechnology intellectual property portfolio and in 2000, MIT’s Technology Review placed one of his patents among the top 5 that “will transform business and technology.”

Williams received a bachelor of arts in chemical physics in 1974 from Rice University and a Ph.D. in physical chemistry from the University of California, Berkeley in 1978. He was a member of technical staff at AT&T Bell Labs from 1978 to 1980 and a faculty member of the Chemistry Department at UCLA from 1980 to 1995.

Michael E. Nelson, Ph.D.
Venable, LLP
Washington, DC
Patenting Small Molecule Therapeutics
Abstract: Not all patents are the same. Patent strategies and the requirement of what constitutes a complete application differ from one field of invention to another.

UCLA Office of Intellectual Property (OIP) partners with Venable LLP to bring to UCLA inventors a seminar on patenting therapeutic small molecule inventions and uses thereof. This subject matter specific seminar (drugs, biomarkers, cell therapy) is part of a series of seminars OIP hopes inventors working on the respective subject matters can attend so that inventors recognize how they can contribute to strengthening patent rights. This ranges from providing the information that is needed to meet certain statutory requirements of patentability (written description and enablement) to brainstorming different permutations of the invention, including consideration on what the product deriving from the invention constitutes, potential modifications that may yield the same intended results, and future products or uses. This contribution and cooperation by inventors are important as we move towards a first to file system (effective March 16, 2013) where we have to balance filing early versus having a complete application that meets the patentability requirements. This session will focus on pharmaceuticals, following a typical discovery-to-development scenario, from turning a target associated with a disease into a screening assay, to identifying active organic compounds, and developing methods of using them. The types of information most relevant to patenting valuable inventions will be discussed for each stage.

Speaker: Michael E. Nelson, Ph.D. is a patent agent at Venable LLP in Washington, DC, who focuses on drafting, prosecuting, and advising clients on intellectual property and patent prosecution of domestic and foreign patent applications. Dr. Nelson’s practice focuses on the chemical and pharmaceutical arts including organic compounds, small molecule therapeutics, organic synthesis processes, natural products, and pharmaceutical formulations. Dr. Nelson also focuses on polymers and organic materials including organic semiconducting, light-absorbing, and light-emitting materials for electronic devices. Dr. Nelson studied Chemistry at the University of Texas at Dallas and earned his Ph.D. in Medicinal Chemistry and Pharmacognosy from The Ohio State University in 2001.

Dr. Nelson’s laboratory research experience includes high-throughput parallel synthesis of small molecules for biological screening; synthesis of complex organic compounds as anti-cancer agents; and synthesis of isotope-labeled small molecules to investigate the biosynthesis of natural products. Dr. Nelson has performed research for the National Institutes of Health, the National Cancer Institute, and the NIH Chemical Genomics Center.

Dr. Nelson also served as a Patent Examiner at the United States Patent and Trademark Office, examining patent applications in the field of organic synthesis, organic semiconducting materials and organic electroluminescent devices.

Dr. Nelson is also currently pursuing a law degree from the Georgetown University Law Center in Washington, DC.

Professor Walter Kohn
Nobel Laureate in Chemistry
University of California, Santa Barbara
Electronic Structure of Matter: Wave Functions and Density Functionals
Abstract: In 1926 Schrödinger published his famous equation which revolutionized all of chemistry and a great deal of physics. In principle, (apart from relativistic effects), it described completely the electronic structure of matter, including atoms, molecules, solids, liquids, and plasmas. However, in practice, unless symmetries radically simplified matters, calculations with “chemical accuracy” were usually limited to systems of ten to twenty atoms.

Beginning in 1964 a new viewpoint, called Density Functional Theory, was developed, which is based on the probability density distribution of electrons in the system in question. Apart from providing additional insights into electronic structure, it has also allowed extensions to much larger systems, up to 500 to 1000 atoms. It has found a great many practical applications in physics and chemistry, for example, to defects in solids, drug design, and biological molecules.

In this talk I will explain the basic ideas of Density Functional Theory, compare its strengths and weaknesses with those of the more traditional wave function approach, and describe some applications.

Bio: Originally from Austria, Walter Kohn studied Mathematics and Physics at the University of Toronto. He then completed his Ph.D. in Nuclear Physics and a postdoctoral fellowship at Harvard University in 1948, followed by postdoctoral work at the Niels Bohr Institute in Copenhagen. Kohn has made major contributions to the physics of semiconductors, superconductivity, surface physics and catalysis. He was the founding director of the Institute of Theoretical Physics at the University of California in Santa Barbara, which is one of the leading research centers in physics. He has received numerous awards including the Niels Bohr/Unesco Gold Medal, the United States National Medal of Science and the Richard Prange Prize. His role in creating Density Functional Theory, the most widely used theory of the electronic structure of matter, earned him the Nobel Prize in Chemistry in 1998. In recent years, he was an active member of the U.S. government’s Basic Energy Science Advisory Committee and a consultant with the National Renewable Energy Laboratory. In 2005 he produced a documentary on solar power entitled “The Power of the Sun.” Kohn currently works on Macular Degeneration, renewable energies and global warming

Understanding the molecule-plasmon coupling
Abstract: Controlling the optical behavior of molecules near the vicinity of noble metal nanoparticles continues to be an active research area in nanoscience. A molecular level understanding of the optical properties of such metal-molecule complexes is important for many applications such as energy harvesting, nanoscale optical circuits, and ultra-sensitive chemical and biological sensors. In this talk we will discuss our recent theoretical studies aimed at understanding the coupling between molecules and plasmons. We will show how electrodynamics simulations can be used to describe the optical properties of mixed exciton-plasmon states arising when strongly absorbing dyes interacts with plasmons. Electronic structure methods will be used to explore the chemical coupling in surface-enhanced Raman scattering (SERS), and resonance effects in SERS and surface-enhanced hyper-Raman scattering.

Protein-Like Functions in a Small RNA Enzyme
RNA enzymes catalyze chemical reaction with just four, similar nitrogenous heterocycles. Yet RNA enzymes share remarkably similar properties to the much more chemically diverse protein enzymes. I will discuss how RNA side chains participate in proton transfer, with pKa's shifted to neutrality. We take an interdisciplinary approach involving mechanistic enzymology, crystallography, Raman spectroscopy, and theory to arrive at a unified mechanism for the ribozyme. These studies show that RNA can approach proteins in terms of intrinsic rates of reaction.

Functional Hybrid Structures of Semiconductor Nanocrystals
Research Interests:
Colloidal semiconductor (quantum dots) and metal nanocrystals. Using the colloidal chemistry approaches we synthesize semiconductor and metal nanorystals of variable sizes, shapes and compositions, tuning the emission of semiconductor nanocrystals and surface plasmon resonances of metal nanoparticles through the visible and near-IR spectral range. Colloidal nanocrystals, with their variable surface chemistry determined by a reach choice of capping ligands are ideal building blocks for fabrication of different hybrid nanostructures. We apply optical spectroscopy to study energy transfer and charge separation in these nanostructures and look for different applications of semiconductor and metal nanocrystals, ranging from photovoltaics and water splitting to biological fluorescent labels and SERS substrates.

Rakesh Agrawal, PhD
Winthrop E. Stone Distinguished Professor,
School of Chemical Engineering, Purdue University
Nobe Founders Lecture: Chemical Engineering in a Solar Energy Driven Sustainable Future
Abstract: Chemical engineering as a discipline evolved in the 20th century with the conversion and use of then abundantly available fossil resources, mainly coal, natural gas and crude petroleum. However, going forward the fossil resources are finite and economic growth, environmental concerns and political landscape are reshaping the availability as well as the manner in which these resources will be used. Ultimately a transition from fossil resource based state to a renewable energy based state is inevitable. Such a transition provides us the same level of dramatic opportunity and growth as experienced by chemical engineers during the early to mid part of the last century.

In this presentation we will focus on a future where the basic human needs of food, chemicals, heat, electricity and transportation will generally be met by solar energy. Transition from fossil resources to such a solar-energy-driven future provides an unprecedented opportunity for chemical engineers. Novel technologies and solutions will be needed to satisfy all the basic needs of daily human life. We will discuss some of these challenges and opportunities to satisfy chemicals, fuels and electricity needs.

In a solar-energy-driven world, it will be particularly challenging to satisfy the need of the transportation sector due to its requirement of high energy density fuel and associated ease of handling. Novel solutions to meet this challenge and sustain the current transportation sector will be presented. These solutions provide a feasible framework for a sustainable solar economy. They also provide exciting possibilities for Chemical Engineers to apply their expertise and contribute to the grand challenge of energy.

Using “Tissue Microbiology” to Obtain a Coherent Picture of Infection
The study of the complex interplay between an infecting organism and its host is a cornerstone of infection biology.

By combining the power of multiphoton-based animal imaging with the precision of micro-surgery, we have developed a system which allows the visual tracking of a live infection within a living animal. Observations begin with the first interactions between host and pathogen. By using GFP expressing uropathogenic E. coli we are able to follow the progressing pathophysiology of pyelonephritis. By so doing, vasal, immune and nephritic events, previously un-described, have been revealed.

Isogenic strains, carrying mutations in virulence factor genes such as a-haemolysin, Type 1 and P fimbriae, are used to address their role for the kinetics of bacterial colonization in vivo as well as the host’s immune and physiological responses. Transcriptional profiling and comparative tissue transcriptomics has revealed a core of 80 genes directing the multi-cellular tissue responses. This demonstrated a marked role of IFN-ã in prompt inter-organ communication.

The ‘all-inclusive’ aspect of intravital studies is the foundation for an emerging field we have termed ‘tissue microbiology’. Because intravital studies deepen understanding of the pathophysiology of infection, they promise to have great value in identifying future treatment regimes.

Imaging Phase Transitions in Viruses
The forces that stabilize macromolecular assemblies such as virus capsids are coordinated on three levels: in the folds of protein subunits; between subunits in oligomeric building-blocks (which can be homomeric or heteromeric); and between building-blocks in higher order structures. Many assemblies undergo concerted conformational changes - in effect, phase changes - at successive stages of their functional cycles. They affect all three structural levels. In the maturation of virus capsids, they control the capsid's physical stability and its ability to interact with other proteins and nucleic acids. We have been using a combination of calorimetry and time-resolved cryo-electron microscopy to investigate thermodynamic and structural aspects of these phase changes. Recently, we came across a different kind of phase-change - one from solid to gas - that occurs in proteins embedded in densely packed DNA. Although, like other radiation damage effects, this bubbling is detrimental to native structure, it can nevertheless be exploited to investigate the internal structure of nucleoprotein complexes.

Long-range mechanical force enables self-assembly of epithelial tubules in fluidic/semi-fluidic phases

Abstract:
Spatiotemporal coordination of cell positioning and differentiation is critical in morphogenesis. Loss of coordination is often a hallmark of tissue abnormality and tumorigenesis. Recent studies indicate the importance of mechanical force in morphogenesis such as tubular pattern formation. However, how cells coordinate mechanical interactions between each other and with extracellular matrix (ECM), to initiate, regulate, or maintain long-range tubular patterns is unclear. Using a two-step process to quantitatively control cell-ECM interaction, we find that epithelial cells, in response to a fine-tuned percentage of type I collagen (COL) in ECM, develop various patterns resembling those observed in tubulo-lobular organs. In contrast with conventional thought, these patterns arise through bi-directional transmission of traction force, but not through diffusible biochemical factors secreted by cells. In turn, the transmission of force evokes long-range (~600ƒÝm) intercellular mechanical interactions. A feedback effect is encountered when the mechanical interactions modify cell positioning, COL alignment, and nucleus signaling. Mathematical modeling and micro-patterning experiments reveal that such feedback is a novel cell-number-dependent, rich-get-richer process, which allows cells to integrate mechanical interactions into long-range coordination. Remarkably, such feedback enables a bi-stability of tissue morphology: lobular or tubular. The spatial scale of coordination is further predicted and verified to be maximized in fluidic/semi-fluidic phases, leading to the formation of a single long-range (~1cm) epithelial tubule (i.e., singularity). We then find that cell differentiation (i.e., apicobasal polarity formation) in the fluidic phase relies on formation of ECM scaffolds around self-assembled lobule/tubules. However, these scaffolds do not cover the entire lobule/tubules, while cells in the no-ECM areas still form polarity. This contradicts current models where cell-ECM contact is assumed to coordinate and maintain polarity. A 1-D free energy model is proposed to account for such unconventional observation. Finally, we show that tumor colonies can use mechanical interactions to develop various invasion patterns. At low [COL], colonies synergistically develop long-range invasive path. At high [COL] or high colony density, colonies form random, independent scattering patterns. Our results have two impacts. First, they suggest a potential mechanism cells can use to form and coordinate long-range tubular patterns, independent of those controlled by diffusible biochemical factors. Second, they provide a new strategy to engineer/regenerate tubular organs using scaffold-free self-assembly.

Hisato Yasumatsu,
Cluster Research Laboratory, Toyota Technological Institute: in East Tokyo Laboratory, Genesis Research Institute, Inc., Japan
Special Seminar: Specific Functions and Phenomena Induced by Electronic and Kinematic Interactions between Cluster and Solid Surface
Abstract: When a cluster encounters a solid surface, novel static and dynamic properties emerge due to significant exchange of electrons and kinetic energies between them, being controlled with the decisive parameters of the atomic composition of the cluster and its collision energy toward the target surface [1]. Therefore, it is true that specific functions and phenomena are expected in such a cluster-surface system. In the present talk, two representative studies on the cluster-surface interaction in the energy ranges of 10 eV and 10 keV will be delivered.

At a collision energy low enough to avoid cluster dissociation, one can fix uni-composition clusters firmly on a solid surface by landing cluster ions mass-filtered out of an cluster-ion beam. Strong nano-space electric field is generated at the interface between the cluster and the surface due to electron transfer between them [2], where one can expect functions relating to catalysis, photoelectric effects, photoreaction, etc. Geometric, electronic and catalytic properties of Pt [2-5] and Pt-Ag bi-element clusters [6,7] on a silicon surface will be presented according to the STM/STS and the temperature-programmed reaction (TPR) experiments. On the other hand, at collision energies much higher than those of local phonons of the target surface and the incoming cluster, one can deposit most of the collision energy into a tiny volume of the topmost layers of the target and the center of the cluster [1], so that a large number of atoms and clusters are ejected from the ultra-hot region in experience of ultrahigh-pressure chemistry [8]. Experimental and simulation studies on the impact of CO2 cluster cations onto a graphite surface will be presented.

Single-molecule sequencing by force: forward and backward motion of replicative polymerases and their coupling with helicases
In the replisome the polymerase collaborates with the helicase to drive the leading strand synthesis. In vitro, the helicases alone appear to unwind the replication fork with a rate far slower than the replicative one. Polymerases alone are even worse when working on a fork substrate that is in strand displacement. On the other hand, coupling the two enzymes leads to a fast and processive synthesis. The understanding of this coupling is far from perfect and was the motivation of our study.

We investigate replicative polymerases and their helicase coupling in single molecule assays using a DNA hairpin in an unzipping configuration. In this simple fork model we assist these enzymes by an external force which provides a control parameter. Modulating the force between 0 and 15pN is a mean to assist a molecular motor opening the fork and thus to replace a partner in the collaborative work. This strategy has already been used to evidence that T7 and T4 helicases display an unwinding rate increasing exponentially with the force. We have conducted this assay with different replicative polymerases, we show that strand displacement polymerization is possible with substantial assisting force level. When the force is reduced we show that the exonuclease activity is dominant. This finding leads to the development of a Cyclic Polymerase Assay (CPA) where a polymerase is periodically switched from polymerization to strand degradation by modulating the assisting force. Such an assay is very convenient to study polymerase activity. Moreover, we present here a single molecule version of the Sanger sequencing method. We shall also discuss other sequencing assay using a DNA hairpin.

Finally, the same assay can also be carried out to study the coupling between helicase and polymerase. We find that the coupled system is very efficient and advances at maximum rate, in stark contrast to the case of the isolated polymerase. We explain this result by a collaborative model where both the helicase and the polymerase are described by the Betterton-Julicher helicase model (Betterton 2003). The helicase is described by a fast passive helicase while the polymerase corresponds to a slow weakly active helicase.

Full-spectrum solar cells based on colloidal quantum dots
To be efficient, solar photovoltaics must match their absorption spectrum to the sun's spectrum reaching the earth's surface. Our group focuses on using colloidal quantum dots "solution-synthesized, solution-processed, quantum-size-effect-tunable materials" to build low-cost solar cells that offer a route to high efficiencies through spectral utilization matched to the sun. The community has made great progress in recent years, achieving 6% solar power conversion efficiencies half a decade after the first reports of infrared solution-processed photovoltaics. Advances include the realization of densely-packed, well-passivated colloidal quantum dot solids based both on short organic and novel small inorganic ligands. I will review the latest advances and discuss the prospects for the field, including the advances in materials chemistry needed to bring CQD PV above 10% solar power conversion efficiencies.

The Use of Nanotechnology for Needle-Free Immunization
Needle-free immunization is a global priority. Currently, no adequate needle free delivery technologies exist. The World Health Organization (WHO) estimates that 30% of the nearly 2 billion immunizations given worldwide each year are unsafe. These account for nearly 21 million people infected with hepatitis B virus (HBV), two million people infected with hepatitis C virus (HCV), and 260,000 new HIV infections annually. Transcutaneous immunization (TCI) is an immunization strategy that specifically addresses this need by combining the clinically proven strategy of vaccination with a lower-cost, safer, and potentially more effective delivery technology. However, several factors have impeded the widespread adoption of TCI, including: 1) limited loading capacity for aqueous-insoluble antigens; 2) inability to encapsulate diverse chemical payloads; 3) high cost of manufacturing which challenges scaled-up production, 4) chemical instability; 5) mechanical instability; and 6) the requirement of costly medical devices such as ultrasound to achieve stratum corneum penetration. Nanopolymersomes, vesicle constructs of diblock copolymers, have the potential to address these limitations and will be the focus of discussion.

Building a "Body-On-A-Chip": Towards Better Drug Development
We seek to understand the response of the human body to various pharmaceuticals. Tissue engineered constructs can play a significant role in drug development. Our platform technology is an in vitro system that combines microfabrication and cell cultures and is guided by a computer model of the body. We call this in vitro system a micro cell culture analog (microCCA) or a "Body-on-a-Chip". A microCCA device contains mammalian cells cultured in interconnected micro-chambers to represent key body organs linked through the circulatory system and is a physical representation of a physiologically based pharmacokinetic model. MicroCCAs can reveal toxic effects that result from interactions between organs as well as provide realistic, inexpensive, accurate, rapid throughput toxicological studies that do not require animals. The advantages of operating on a microscale include the ability to mimic physiological relationships more accurately, as the natural length scale is on the order of 10 to 100 microns.

We have done "proof-of-concept" experiments on two systems to evaluate combination therapy for cancer. The first system evaluated possible combination therapies for multidrug resistant (MDR) cancer using the chemotherapeutic drug, doxorubicin, and two MDR suppressors: cyclosporine and nicardipine. The system demonstrated that a combination of MDR suppressors was more effective than using a single type of suppressor. We have also used a microCCA to test potential combination therapies (Tegafur and uracil) for colon cancer. Tegafur is a prodrug for 5-FU, and uracil is an inhibitor of DPD, an enzyme that deactivates 5-FU. Simple microwell plates cannot probe this system, but the microCCA predicts the types of responses observed experimentally. A "pumpless" system that would be easier to utilize has been demonstrated with Tegafur also. We have coupled these body modules with a micro model of the GI tract to examine the response to oral exposure of drugs, chemicals, or nanoparticles.

Overall, we believe that in vitro microfabricated devices with cell cultures provide a viable alternative to animal models to predict efficacy and toxicity in response to pharmaceuticals.

"Pathogen-Mimicking" Nanoparticles for Prevention and Treatment of Respiratory Infectious Diseases
The design of vaccines and therapeutics to address respiratory infectious diseases is fraught with challenges ranging from the need for cold storage to poor immunogenicity to the need for multiple doses to the need for needle-based methods that require medical professionals to administer. In this talk, we describe the molecular design of a safe, non-toxic, and efficacious nanoparticle-based platform that can address the challenges mentioned above and provide a robust technology to address both pre- and post-exposure to respiratory pathogens. These degradable nanoparticles are based on amphiphilic polyanhydrides, which degrade by hydrolytic cleavage of the anhydride bond. We have shown using a bottom-up approach that vaccine adjuvants based on amphiphilic polyanhydride nanoparticles are capable of mimicking a natural infection and inducing an immune response that provides long-lived protection against a subsequent challenge. These hydrolytically degradable materials possess the unique ability to mimic pathogens with respect to persisting within and activating immune cells.

Our studies have shown that these nanoparticles are safe when administered via multiple routes - intranasal, subcutaneous, and intramuscular. These particles are stable at high temperature for extended periods of time obviating the need for cold storage, which is a major hurdle in the deployment of vaccines to remote regions of the globe. The particles are effectively taken up by immune cells and like many pathogens, they quickly distribute to tissue sites distal to the site of administration. These nanoparticles can be used to encapsulate vaccine antigens and/or antibiotics and deliver them in a sustained manner to immune cells. Using Yersinia pestis, a respiratory biodefense pathogen which causes pneumonic plague, as an example, we have shown that nanoparticle-based vaccines confer full protection in a single dose administered intranasally ten months prior to lethal challenge. Additionally, these particles can be used to effectively deliver antibiotics intracellularly in a single administration, which has important implications for patient compliance, dose sparing, and cost savings. This rational approach for designing novel amphiphilic materials as nanoscale adjuvants and therapeutics has the tantalizing potential to catalyze the development of next generation technologies against emerging and re-emerging diseases.

Science and Dermatology: More than Skin Deep
The skin is the largest organ of our body and plays a crucial role in protecting the host. While skin appears to be a mere covering of our body, it is a rather well-organized, complex organ, both at a cellular and molecular level, which provides multiple functions for the host. The skin is best thought of as an immune organ and the first line of defense. During this talk, Dr. Kim will discuss skin immunity and the sophisticated protective mechanisms that keep us healthy. She will also discuss what happens when the same mechanism goes awry and leads to inflammation, injury and a disease state. This talk will highlight how the science of dermatology can be more than skin deep and its application can be utilized by all disciplines for applied sciences.

Criticality in brain's physics and mind dynamics
It is well known that dynamical systems posed near a second order phase transition generate a bewildering variety of robust and flexible behavior, associated with the abundance of metastable states at the critical point. This universal feature led us to argue, since the last millennium, that the most fundamental cognitive properties of the functioning brain are only possible because it is spontaneously located at the border of such instability. In this talk we review the motivation and then describe recent experimental results, both in health and disease, at various brain scales ranging from a few millimeters up to the entire cortex. Finally we will discuss which aspects of the mind dynamics can be usefully explained in terms of critical phenomena, as well as the lesson and implications for building emerging intelligent devices.

Engineering Hope with Biomimetic Systems
Research in biomimetics has progressed rapidly in the recent years fueled by the unique interdisciplinary efforts fusing engineering, medicine, and biology. This research has to address the aspects of humanity and societal impacts, technical challenges and barriers, targeting a wide range of applications. These applications span from understanding the highly complex biological systems, to treating/restoring/repairing the lost biological functions such as deafness, blindness, seizure, and paralysis, to building human-machine interface for performance enhancement. Biomimetic systems will offer viable solutions to neural disorder diseases which potentially affect very large population of people worldwide and thus occupy large market share in healthcare.

The success of biomimetic systems depends on several major enabling technology include biological recording, stimulation, bio-signal processing, wireless communication, sensing, electrode, hermetic packaging, and powering, where the implants must deal with critical constraints of size, power, reliability, safety, and technology. This talk will define enabling technologies and challenges to realize integrated and miniaturized biomimetic systems, especially neural implants, which can be used for building advanced neuroscience and neuroprosthetics platform with closed-loop control mechanisms. We will cover the development history, market opportunity, technical challenge/barriers, enabling technology, and application examples.

From understanding neural plasticity to development of cognitive enhancers
Defects in neuronal migration as well as formation and pruning of synaptic contacts lead to abnormal brain function in various neurological disorders and neurodegenerative diseases. Understanding the signaling mechanisms that underlie the establishment of neuronal connections is therefore pivotal for identifying new targets and developing neurotherapeutic agents. My laboratory has been interested in deciphering how receptor tyrosine kinases (RTKs) and their downstream signaling molecules relay extracellular signals that are crucial during nervous system development and functioning. In this talk, I will discuss how the Rho GTPase regulator α2-chimaerin, a signaling protein activated by the RTK EphA4, regulates neuronal migration and how EphA4-mediated signaling regulates the abundance of glutamate receptors to maintain the stability of neuronal network during homeostatic plasticity. Furthermore, we have established a focused knowledge-based drug discovery program to search for novel drug leads from traditional Chinese medicine (TCM). This TCM-based strategy has been adopted to identify novel lead compounds that modulate synaptic functions and therefore represent potential therapeutic agents for neurological disorders. In this talk, I will discuss the cognitive enhancing effect and the underlying mechanisms of one of the novel lead compounds identified through this strategy.

Our lab's research has focused on imaging, manipulation, and spectroscopy at the nanoscale including the investigation of single molecule electronic and mechanical devices, and the development of a new imaging technique based on the mathematics of compressive sensing. To build and understand the mechanics of nanoscale motion and manipulation in molecular systems, we have used scanning tunneling microscopy (STM) to probe a family of molecules based around the concept of the Nanocar. I will highlight our recent work with various molecular wheels including fullerenes, carboranes, and ruthenium compounds. In addition to single molecule mechanics, we have employed STM to study conducting polymers and graphene as candidates for future electronic devices. Lastly, we have built an imaging system by coupling an optical modulator, a single detector, and the mathematics of compressive sensing. Benefits of our scheme include greater sensitivity and lower cost imaging beyond the visible spectrum as well as the implementation of a compressive confocal microscope system.

CIGS Photovoltaics: A Path to Grid Parity
For many years, renewable energy research has chased grid parity, i.e. the point at which the cost of electricity from renewables equals that from traditional sources. For the first time in history, isolated pockets of grid parity have occurred for multiple renewable generation methods. Plausible paths to widespread grid parity for photovoltaics around 2015 exist. However, aggressive improvements to both module and non-module costs are needed. This presentation discusses the current status of CuInxGa1-xSe2 (CIGS) thin-film photovoltaic technology and manufacturing relative to grid parity, and where opportunities for improvement exist.

Epitaxial Graphene: Growth and Doping
The growth of high quality epitaxial graphene will facilitate the development and commercialization of graphene nanoelectronics devices, and the main substrate-based approaches are chemical vapour deposition (CVD) on metal catalytic thin films and thermal decomposition of silicon carbide (SiC). We have performed detailed studies using in situ scanning tunnelling microscopy (STM), synchrotron photoemission (PES) and density functional theory (DFT) calculations to investigate the structure of the various reconstructions of 6H-SiC(0001) prior to its thermal decomposition to form epitaxial graphene (EG). We show that the transition from monolayer EG to trilayer EG adopts a bottom-up growth mechanism, and x-ray absorption fine structure studies indicate an increase in disorder of Si atoms in the SiC substrate beneath the surface and the formation of Si clusters.

A major challenge in graphene-based devices is opening the energy band gap and doping. Molecular functionalization of graphene is one approach to modifying its electronic properties. Surface transfer doping by surface modification with appropriate molecular acceptors represents a simple and effective method to non-destructively dope graphene. Surface transfer doping relies on charge separation at interfaces, and represents a valuable tool for the controlled and non-destructive doping of semiconductors and nanostructures at relatively low cost, thereby facilitating the development of hybrid organic-graphene nanoelectronics. Molecular self-assembly of bimolecular systems on epitaxial graphene and HOPG is demonstrated. Surface transfer hole doping of epitaxial graphene using oxide thin films is also discussed.

Weighing Nanoparticles and Cells with Microchannel Resonators
Microchannel resonators are MEMs-fabricated, vacuum-packaged fluidic microchannels whose mechanical resonant frequency changes in response to the mass they contain. With femtogram (10-15 g) resolution, these sensors can measure the mass, density, and size of individual micro- and nano-scale particles with resolution and accuracy that surpasses mature technologies such as light scattering. This talk will survey the capabilities and applications of this technology for nanoparticle characterization, as well as efforts underway to push the mass sensitivity toward nanoparticles and viruses as small as 10 nm. In addition, gentle fluidics allow measurement of living bacteria, algae, and mammalian cells with resolution far beyond conventional methods such as the Coulter counter. Monitoring the growth of individual cells is enabling fundamental studies of the cell cycle, cancer, and drug susceptibility.

Novel Ways To See and Recognize Life!
New Life Science AFM/ILM Imaging Workshop
RSVP to nanopicolab@cnsi.ucla.edu

Recognition Imaging: Tracking Nanoscale Biochemistry
Stuart Lindsay, Ph.D. (The Biodesign Institute at Arizona State University)
Recognition imaging generates simultaneous maps of topography and chemical identity in real-time AFM images. It utilizes a recognition ligand attached to the AFM probe via a flexible tether. Antibodies have been used extensively, though in some cases we have obtained better selectivity with DNA aptamers. Applications include the chromatin remodeling and identification of post-translational modifications of histones. We are also developing a three-way linker to co-locate factors in images. This works by first imaging with two recognition ligands, blocking one, and then re-imaging. Thus, two different factors can be identified with nanometer precision in one field of molecules.

Combined AFM/ILM Imaging Applications for the Life Sciences
W. Travis Johnson, Ph.D. (Agilent Technologies)
The resolution of a standard optical microscope is limited by the wavelength of light. In contrast, image resolution with an AFM is limited only by the radius of the tip of the AFM probe. With an AFM, high-resolution images of living cells, proteins, and nucleic acids can be obtained under physiological conditions. A combined AFM/ILM system provides data complementary to information obtained via either technique alone. For example, such a system provides accurate positioning of samples under the AFM probe. A combined system can also be used to gather cell morphology information, biomechanical data, and information regarding the architecture of membranes, cellular processes, organelles, and cytoskeletal structures.

Demonstration
Following lunch, there will be a demonstration of the new Agilent 6000ILM AFM, a system that seamlessly integrates the capabilities of an atomic force microscope (AFM) with those of an inverted light microscope (ILM) or confocal microscope.

Controlling the Property of Graphene with Adatoms
I will discuss our work on fluorinated graphene. In the limit of very dilute fluorination, fluorinated graphene undergoes a carrier density driven metal-insulator transition, exhibiting weak localization at high densities and variable range hopping at low densities. In the hopping regime, the system displays a very large negative magnetoresistance in a perpendicular magnetic field. The zero field resistance is reduced by up to a factor of 40 and has yet to saturate at 9 Tesla. Possible explanations include adatom-induced magnetism and interference-driven Anderson localization. In the opposite limit of full fluorination, we demonstrate the synthesis of nanocrystalline graphene monfluoride, CF. We show evidence of the structure and vibrational modes of CF Transport measurements indicate a large band gap with strongly insulating behavior. Photoluminescence studies reveal several emission modes in the visible range. Their temperature dependence points to sub gap defect states. The band edge emission of CF has yet to be found, likely in the deep UV.

Nanoscale IR Spectroscopy using an AFM
The ability to unambiguously identify arbitrary material under the tip of an Atomic Force Microscope (AFM) has long been identified as one of the primary interests of users of probe microscopy. While the AFM has the ability to measure a range of material properties including mechanical, electrical, magnetic and thermal, the technique has lacked the robust ability to characterize and identify unknown materials. Infrared spectroscopy is a benchmark technique routinely used in a broad range of sciences to characterize and identify materials on the basis of specific vibrational resonances of chemical bonds. Several AFM probe-based techniques have been used to beat the diffraction limit of conventional IR measurements, including near field optical techniques. Other IR techniques are based on measuring the local temperature rise from spectral absorption through the use of temperature-sensing probes integrated with conventional Fourier Transform IR (FTIR) spectrometers. To our knowledge, however, none of these techniques provide readily interpretable broadband IR spectroscopy with nanoscale resolution. We have successfully integrated the capabilities of AFM with IR spectroscopy to allow chemical characterization on the micro and nanoscale. The instrument employs a technique called photothermal induced resonance (PTIR) that uses an AFM probe to measure the local thermal expansion from IR light incident upon a sample. This technique enables the ability to obtain a high quality IR spectrum at a selected point in an AFM image and/or automatically map spectra at an array of points on a sample to enable chemical mapping. In addition, local mechanical and thermal properties can be obtained from the sample. In this presentation, we will share the details of the measurement technique including application examples on polymer multilayers and blends, along with measurements on biological samples.

Gold Nano-Island Films: Properties and Sensing Applications
Gold nano-island films prepared by evaporation on transparent substrates and annealing, display a localized surface plasmon resonance (LSPR) extinction band whose intensity, wavelength and shape are sensitive to the film morphology and the refractive index (RI) of the adjacent medium. Such systems are useful as optical transducers in label-free sensing based on RI change induced by binding of an analyte to a recognition interface on the Au islands, carried out using common spectrophotometry-based instrumentation.

Here we study the preparation on glass substrates of Au island films with tunable morphology and optical properties using discontinuous, evaporated Au layers as well as continuous layers which undergo depercolation upon annealing. The mechanism of structural transformation is influenced by the initial structure of the Au film, which varies with the nominal thickness. High-temperature annealing induces partial island embedding in the glass, thereby stabilizing the morphology and optical response. The RI sensitivity (RIS) of thermally depercolated films shows exceptionally high values, up to ca. 700 nm / RI unit. Optimization of the transducer performance requires determination of the RIS and plasmon decay length, both dependent on the Au island film morphology.

Biological applications of LSPR transducers based on evaporated / annealed Au nano-island films are demonstrated using several biological systems showing specific receptor - target analyte interactions, including proteins, carbohydrates and polynucleotides. Specificity and sensitivity are achieved by immobilization of the receptors on optimized Au island films and use of a flow-cell configuration. The results indicate that LSPR transducers comprised of Au nano-island films provide a convenient, inexpensive and sensitive system for studying biomolecular interactions and for label-free biosensing applications.

Engineering The Next Generation of Cancer Therapeutic Enzymes and Antibodies
Our lab is broadly interested in the development of platform technologies for the discovery and pharmacological development of therapeutic proteins, especially for cancer. In recent years, there has been intense interest on the metabolic abnormalities displayed by cancer cells and how these effects may be exploited for therapeutic purposes. The use of enzymes to systemically deplete metabolites required for the growth of tumor cells, but not of normal tissues, has been pursued for many years. However, with the exception of childhood leukemia (ALL) where administration of the bacterial enzyme, asparaginase, has been shown to have significant therapeutic benefit, there are no other enzyme drugs for cancer treatment. This is because bacterial enzymes elicit strong adverse responses due to immunogenicity, whereas human enzymes that display either the proper catalytic activity or pharmacological properties for reactions relevant to cancer therapy are not available. We have been using protein engineering strategies to create human enzymes that display new catalytic properties of therapeutic relevance and also the proper stability and in vivo persistence appropriate for therapeutic applications. We have developed a family of such therapeutics for various malignancies. One such example, an engineered human arginase I for the treatment of liver cancer and metastatic melanoma is now in advanced preclinical development.

In parallel, we have been developing a number of technologies for the isolation of IgG antibodies to cancer antigens and for the enhancement of Fc-mediated effector functions. A summary of this work will also be presented.

Engineered Biotic/Abiotic Materials and Interfaces for Understanding and Controlling Biology
In recent work we have shown that yeast, bacterial, and mammalian cells, when introduced into self-assembling solutions of phospholipids and soluble silica, serve as living colloids directing the formation of unique biotic/abiotic interfaces and architectures through cellular response pathways such as the high osmolarity glycerol pathway observed in yeast. The result is a lipid-associated cellular interface coherently incorporated within a surrounding lipid templated silica nanostructure. This structure preserves cell viability under externally desiccating conditions allowing probing of the behavior of individual cells for the first time under conditions of complete chemical and physical isolation. For individual Staphylococcus aureus, we show that self-signaling within this confined environment induces genetic re-programming of the cell according to a two-component regulatory pathway normally associated with high cellular density i.e. 'quorum sensing'. This 'discrete' quorum sensing allows S. aureus to sense confinement and to activate virulence and metabolic pathways needed for survival. Overall we show that cellular confinement within self-assembled and lithographically defined environments reinforces chemically and mechanically induced pathways recently recognized as being important in controlling behavior of not only bacteria but also cancer. Turning these lipid-associated silica nanostructures inside out, we have also recently explored lipid bilayers supported on mesoporous silica nanoparticles (aka 'protocells') as a new nanoparticle delivery agent, allowing the targeted delivery of arbitrary cargo to arbitrary cancer with unprecedented specificity. Compared to current liposomal delivery agents, protocells show a million-fold greater killing efficacy.

Shape-Controlled Synthesis of Metal Nanocrystals
Control of nanocrystal shape may initially seem like a scientific curiosity, but its goal goes far beyond aesthetic appeal. For metal nanocrystals, shape not only determines their intrinsic chemical, plasmonic, and catalytic properties but also their relevance for electronic, optical, and sensing applications. Part of our research over the last decade has focused on shape-controlled synthesis of noble-metal nanocrystals. While the synthetic methodology mainly involves solution-phase redox chemistry, we have been working diligently to understand the complex physics behind the simple chemistry - that is, the nucleation and growth mechanism leading to the formation of nanocrystals with specific shapes. Polyol synthesis of silver nanocrystals provides a good example to illustrate this concept. We discovered that the shape of silver nanocrystals are dictated by both the crystallinity and shape of nanocrystallite seeds, which are, in turn, controlled by factors such as reduction rate, oxidative etching, and surface capping. The same mechanism also works for other systems including gold, palladium, and platinum. The success of these syntheses has enabled us to tailor the electronic, plasmonic, and catalytic properties of noble-metal nanocrystals for a range of applications.

How far can we play with molecules?
Self-assembly of functional organic molecules and nano-entities plays increased important role in modern science and technology. Self-assembly processes are mainly classified as static self-assembly and dynamic self-assembly (similar to self-organization). While the current understanding of self-assembly comes from the examination of static systems, much less attention is paid to kinetic effects on self-assembly process, and mechanistic details of dynamic self-assembly are poorly understood. In this talk, different issues concerning self-assembly of organic molecules on surfaces will be outlined. It is aiming to address the question: how far can we play with molecules in order to organize them into systems with advances functions?

Electronic states, magnetism, and transport in partially fluorinated and hydrogenated graphene
It has been demonstrated beyond any doubt that graphene, a single plane of carbon atoms in the honeycomb lattice, has excellent and fascinating electronic properties including very high mobility almost independent of doping, quantum Hall effect at room temperature, and magnetism. In order to harness this potential into devices and electronic applications, we need to find a way to confine charge carriers in graphene. We will review on possibility of confinement based on the chemical functionalization of graphene with hydrogen or fluorine. The fluorination of graphite has been known for many years while hydrogenation is a recently demonstrated possibility. Both show interesting similarities and differences due to the different electronegativity of the adatoms. We will show that this functionalization opens the way to study much more than simple graphene devices. The functionalized structures show a full set of interesting properties such as Kondo phenomena, variable range hopping, and anisotropic magnetism.

Single Molecule Approach towards Modulating Peptide Aggregation Behavior by Using STM
The fine folding and assembling characteristics of amyloid peptides are keen to the pharmaceutical studies of drug molecules and pathological analysis at molecular level for neurodegenerative disorder processes such as Alzheimer's disease (AD). We present the observations of multiple folding characteristics of amyloid peptide by using scanning tunneling microscopy (STM). Molecularly resolved core regions of the peptide assembly structures are identified. In addition, a single molecular approach can be developed using chaperon-like molecular modulators for modulating the aggregation behavior of vital analogues of amyloid peptides relating to Alzheimer's disease (AD), diabetes, etc. In addition, it is identified that the introduction of chaperon-like modulators (terminus molecular modulators: agents interact with C terminus of peptides and side group molecular modulators: agents interact with side group of peptides) could regulate the peptide assembling behavior at molecular level via hydrogen bond and hydrophobic interactions. Chaperon-like modulators affect assembly behaviors as well as the morphology of beta-amyloid peptide aggregates. Furthermore, the modulators could significantly accelerate the aggregation of peptide in aqueous solution and lead to varied cytotoxicity. The results provide a novel approach towards modulating Aβ peptide aggregation.

Microbots as Nanotechnology tools. Catalytic nanomachines
Abstract: Recently a lot of attention has been dedicated towards development of man-made synthetic catalytic micro- nanomotors which try to mimic biological counterparts in terms of propulsion power, motion control and speed. Here we show wireless control of self propelled catalytic Ti/Fe/Pt rolled up microtubes (microbots) which are used to perform various tasks such as selective loading, transportation, assembly and delivery of microscale objects in a fluid: polystyrene particles, thin metallic films (?nanoplates?) and mouse neurons (Catecholamines). Microrobots are self-propelled by ejecting microbubbles in a fluid via catalytic decomposition of hydrogen peroxide into oxygen and water in the presence of platinum film and their motion is controlled by and external magnetic field.

Biography: Samuel Sanchez received his PhD at the Autonomous University of Barcelona,Spain, in 2008. He studied and developed new composite materials for the construction of electrochemical biosensors based on soft polymers, carbon nanotubes, and metallic nanoparticles. After one year as Assistant Professor at the Autonomous University of Barcelona, he joined the ICYS at the International Research Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science, Japan, in February 2009 in a tenure track position. He is currently working on the development of micro/nanorobots based on the nanotechnology of bimetallic nanowires and rolled-up microtubes. He will be Group Leader at IFW, Dresden (Germany) from May 2010.

Angus I Kingon
Professor of Engineering and University Chair of Entrepreneurship and Organizational Studies
Brown University
Increasing the Impact of University Research
In the presentation, Professor Kingon will discuss the role we play as faculty members in ensuring that there is commercial and social impact for our research. He will begin with a macro-perspective: how well are we doing as a university in maximizing the commercial and social outcomes from our (substantial) investment in scientific research? Then from the perspective of an individual faculty member - is it my responsibility to assist in commercialization? To what extent? Is it acceptable to want to create wealth from my research? Or how do I better connect to industry to develop collaborations?

In this presentation he will discuss selected results from the literature on university commercialization of research. He will focus on the obstacles to commercialization activities, from both a macro and faculty perspective, and discuss solutions, followed by a presentation of the results of recent "action-based based research" on improving the commercial outcomes. Professor Kingon will illustrate the talk with two examples of programs (both funded by NSF) that improve commercialization outcomes. One program integrates the entrepreneurship education of graduate students with the establishment of high growth potential new ventures. The second program facilitates the efficient interaction of faculty and post-docs with industry partners in exploring new opportunities that may emerge from the research.

Angus Kingon is Professor of Engineering, and Barrett Hazeltine University Professor of Entrepreneurship and Organizational Studies at Brown University as of 2008. He is the Academic Director of the Commerce, Organizations and Entrepreneurship program, and the co-Director in the graduate Masters-level Program on Innovation Management and Entrepreneurship (PRIME) at Brown University.

"Self and Directed Assembly of Single Molecule Environments"

LIVE FROM CNSI / UCLA

We place single molecules and larger groups into precisely controlled environments on surfaces. The monolayer matrices and the inserted molecules can be designed so as to interact directly, to give stability or other properties to supramolecular assemblies. New families of molecules are being developed to yield even greater control and are enabling determination of the key design parameters of both the molecules and assemblies. This in turn is enabling controlled chemical patterning from the sub-nanometer to the centimeter scales. At the same time, a suite of tools is being developed to give unprecedented information on the structures and properties of these assemblies.

"Using Self-Assembled Monolayers and Mass Spectrometry for BioChip Applications"

LIVE FROM NORTHWESTERN UNIVERSITY

Biochips are prepared by applying an array of proteins, peptides, carbohydrates or other molecules to a flat substrate. They are used to profile enzyme specificities, profile cellular lysates for enzymatic activities, perform high throughput screening, and other applications. Yet, challenges in immobilizing biomolecules in a functional state and in developing label-based formats to assay biochemical chemical activities still limit the use of these tools. This talk will describe an approach for using mass spectrometry to analyze biochips-including enzyme-mediated reactions of immobilized biomolecules and protein-protein interactions. The method is based on self-assembled monolayers of alkanethiolates on gold that present proteins and small molecules with control over the densities, patterns and orientations of these species. The chips are compatible with matrix-assisted laser desorption ionization mass spectrometry and therefore do not require fluorescent or radioisotopic labels for analysis. This technique, termed SAMDI MS, can efficiently monitor a broad class of enzyme activities-including kinase, protease, methyltransferase and carbohydrate-directed modifications-and can detect proteins having molecular weights up to 100 kD. The talk will describe examples that use peptide arrays to characterize enzyme function.

From Biological Design Principles to Bioinspired Nanotechnologies
The burgeoning field of Nanotechnology offers exciting new approaches to attack fundamental questions in biology, create smart medical devices, and positively impact human health. Creation of biologically-inspired nanotechnologies also could revolutionize how materials are designed and manufactured for industrial, aerospace and military applications. But the fields are constrained by a lack of understanding of how living cells and tissues are constructed so that they exhibit their incredible organic properties, including their ability to change shape, move, grow, and self-heal. These are properties we strive to mimic, but we cannot yet build man-made materials that exhibit these features, or develop devices to selectively control these behaviors. To accomplish this, we must uncover the underlying design principles that govern how cells and tissues form and function as hierarchical assemblies of nanometer scale components. In this lecture, I will review work from my laboratory and others which has begun to reveal these design principles that permit self-assembly of 3D structures with great robustness, mechanical strength and biochemical efficiency, even though they are composed of many thousands of flexible molecular scale components. We also are beginning to understand that biological materials are simultaneously "structure and catalyst": the molecular lattices that form the frameworks of our cells and tissues combine mechanical functions and solid-phase biochemical processing activities. In the course of the lecture, I also will describe how recently developed nanotechnologies have been used to create model systems for biological studies, and how they have led to new approaches to interface living cells with microchips, control mammalian cell and tissue development, and probe the process of mechanotransduction - how cells sense mechanical forces and convert them into biochemical responses. Finally, the more fundamental question of how nanoscale structural networks impact information processing (signal transduction) networks to control cellular "decision-making" also will be explored. Understanding of these design principles that govern biological organization is critical for any nanotechnologist who wants to harness the power of biology.

Embodied active sensing in the rodent vibrissa system
In nature, sensation is partly a behavioral process, in which organisms actively acquire and modify sensory information through self-motion (e.g. eye motions or scanning with fingertips). The choice of motions depends in general on goals and context. Also important, though not as well studied, is the dependence of these active sensing choices on the physical embodiment of the organism (e.g. the optical structure of eyes or mechanics of fingertips).

I will outline a combined experimental and theoretical approach to these themes built around the rodent vibrissa (aka whisker) tactile sensory system. A first step in this approach is our quantification of vibrissa "micromotions" believed to underlie tactile texture discrimination in freely behaving animals, an advance enabled by the development of novel high speed (>3000 Hz) videographic and computer tracking methods. We find the animal's embodiment has a marked influence on pre-neural tactile inputs, for example through mechanical resonances in the vibrissae. Moreover, micromotions in freely behaving animals differ substantially from stimuli typically utilized in anesthetized neurophysiology studies, raising questions of how well such studies can be extrapolated to natural contexts.

I will then describe ongoing experiments integrating the videography with neurophysiology. Using chronically implanted multi-electrode "hyperdrives" in primary somatosensory cortex, we record neural activity during tactile behaviors. In addition, we have recently begun to combine the recordings with direct alteration of the activity of the cortical circuit through "optogenetics", the optical stimulation of genetically targeted neural subpopulations (e.g. specific interneuron subtypes). I will sketch preliminary work attempting to unify experimental observations and predictions via computational modeling of the processes by which rodents choose how to gather information from the world, and utilize that information to make decisions. I will conclude by discussing applications to rodent disease models.

Three innovations in bio-acousto-optics
Laser beam steering using acousto-optic deflectors is superior to the more widely used electromechanical scanning methods for its greater speed and lower latency, random access in constant time, insensitivity to environmental perturbations, and intrinsic lensing ability which enables access in three dimensions with no macroscopically moving parts. I will describe three little technological advances in acousto-optic 3D scanning microscopy that solve several long-standing obstacles to its wider adoption: a way of shrinking an entire acousto-optic microscope down to a size suitable for head-worn or hand-held deployment; a way of quickly superresolving fluorescent objects in three dimensions within large volumes; and a way of making an acousto-optic microscope confocal with the aid of a CMOS descanner. I will explain the biological motivations behind these advances and discuss their implications for the future of imaging fast neuronal activity in the intact brain.

Unlocking the Power of Classical and Quantum Optics in Biology: Applications to New Tools for Neuroscience and Fundamental Biological Questions
In the recent years from the intersection of physics and biology, significant advancements in life sciences have emerged. This development has been fueled by two main drivers. On one hand many biological fields and neuroscience in particular, are currently limited by the available tools; hence the development of new physical techniques and methods have enabled new biological discoveries. On the other hand, a physics based approach to addressing biological questions can lead to an understanding of biological problems on a more fundamental level. In this context I will discuss a few developed and planed approaches to structural and functional imaging in neuroscience and understanding of biological function at molecular to atomic scale.

We have developed a super-resolution imaging technique (PALM) based on serial activation and excitation of photoswitchable fluorescent proteins, which allows optical imaging of intercellular protein distributions at nanometer resolution. By combing this technique with an approach to control the optical pulse duration at different axial locations, we have recently extended this technique to three dimensions and to thick biological samples.

In a different project, we have developed schemes for optical control of neural activity via multi-photon activation of genetically expressible ion-channel proteins such as Channelrhodopsin. This technique will allow studies of neural connectivity and mechanisms of neural integration on the single neuron level. By integrating this technique with optical methods for nano-scale voltage sensing, we are currently working towards a scheme for full optical control and recording of neural activity.

Finally, I will discuss ideas about how the application of femtosecond correlation spectroscopy might be used for studying coherent energy transport phenomena in bio-molecular complexes with metal-ion binding domains such as ion-channels and enzymes.

Investigating neuronal plasticity using microfluidic devices
Neurons exhibit remarkable plasticity both in their morphology and in the strength of their synaptic connections. The complex connectivity of neuronal networks within the intact brain, however, presents extreme challenges for studying the cell biology of plasticity in axons, dendrites, and their synapses. During this seminar I will discuss the development and use of microfluidic devices to create organized connections between cortical neurons, providing unprecedented access to different neuronal populations and their subcellular compartments for measurements and manipulations. I will also discuss unique investigations of neuronal plasticity using these microfluidic devices. Axonal protein synthesis is a process which provides some autonomy to axons in order for them to respond to local conditions distal from their cell bodies (e.g., following axonal injury and during growth cone regeneration). Axons are known to locally translate mRNA in invertebrate as well as mammalian peripheral nervous system (PNS) neurons, yet little is known about mammalian cortical axons due to the technical challenges of accessing their axonal compartments. Using microfluidic devices, we have recently identified a large mRNA population in mature cortical axons, providing evidence that these axons have the capacity for local protein synthesis. This work also shows that the mRNA profile in cortical axons has similarities to the mRNA profile in regenerating PNS axons, suggesting a common function for axonal protein synthesis following injury in both these types of neurons. Second, I will discuss work to investigate synaptic plasticity using newly developed microfluidic devices. I will discuss my work to access and manipulate synaptic regions at the micron level for the purposes of investigating synapse to nucleus signaling as well as for investigating local changes at synapses.

Chemistry in Ancient Times: The Invention of Blue and Purple Pigments
Blue and purple materials are not found in surface soil and prevented prehistoric mankind to have access to blue and purple pigments. Only after mining came up about 3000 BC, the rare gemstone Lapis Lazuli became available, which was then also used as a stable, but precious, blue pigment. Ancient mankind "lived" color and the demand for blue and purple pigments became so enormous that it could not be satisfied with Lapis Lazuli alone. In various civilizations this triggered the development of respective pigments by aid of chemistry.

Ancient Egyptians invented Egyptian Blue, a calcium copper silicate (CaCuSi4O1O) constituting a defined chemical compound, which came into use already in predynastic Egypt more than 3000 years ago. Later Egyptian Blue spread into Mesopotamia, Persia and was furthermore utilized by the ancient Greek and also the Romans in the Mediterranean area till the fall of the Roman Empire. Egyptian Blue was used to color vitreous materials, such as faience objects and frits, but also was used as a paint and in compact body artifacts. It was prepared at temperatures of 800 °C from limestone, sand and a copper mineral in the presence of a flux, such as papyrus ash, rock salt or Trona, a mixture of salts with sodium sulfate as the most effective constituent.

Earlier and recent studies of ancient Chinese polychromy revealed that three man-made barium copper silicate compounds were used as pigments or in compact body objects: BaCuSi2O6 (Chinese or Han Purple), BaCuSi4O1O (Chinese or Han Blue), chemically related to Egyptian Blue, and BaCu2Si2O7 (to be denoted as Chinese or Han Dark Blue) (see phase diagram Figure below). The forth phase of the BaO/CuO/SiO2 phase diagram, Ba2CuSi2O7, was apparently not prepared and used as a pigment. While the Ba/Cu 1:1 compounds were utilized from late Western Zhou Period (approx. 800 BC) till the end of Han Period (approx. 200 AD), BaCu2Si2O7 appeared as a pigments on only a few objects of the Han Period. Synthetic access to the barium copper silicate compounds was a difficult task in ancient times, as it is still nowadays in particular with respect to the preparation of high quality materials. Historically the compounds were obtained by flux syntheses at temperatures between 850°C and 1000°C applying appropriate stoichiometries of the starting materials.

All the original Chinese samples investigated up to now contained lead. The addition of lead turned out to be an ingenious chemical trick crucial to synthetic success, in particular when the very stable barite mineral (BaSO4) was used as a barium starting material.

Maya Blue is the youngest of the three artificial historic pigments and was developed and used by the Indians of central America from about 400 AD on. Chemically it is based on indigo, which is intercalated into white clays (Palygorskite and Sepiolite) at temperatures between 200 and 400 °C, thus effecting stabilization of the organic dye and turning it into a pigment.

Based on their chemistry and the availability of starting materials, the geography and the historic developments of these blue and purple pigments will be reviewed.

Thousands of Catalysts for Olefin Metathesis: Variability, Longevity, and Asymmetry at the Metal
Complexes of the type M(NR)(CHR')(OR")2 (M = Mo or W) are established high oxidation state olefin metathesis catalysts, whose overall efficiencies depend dramatically upon the electronic and steric characteristics of the NR and OR" or (chiral) diolate groups. Complexes of the type M(NR)(CHCMe2R')(OR)X (MonoAlkoxidePyrrolide or MAP) species are remarkably active catalysts that are asymmetric at the metal. The latter property can be exploited through synthesis of M(NR)(CHCMe2R')(OR*)X species in which OR* is an enantiomerically pure alkoxide. Such species have been employed (inter alia) for a relatively short and enantioselective synthesis of the Aspidosperma alkaloid, quebrachamine (96% ee). This approach to asymmetric metathesis takes advantage of controlling the chirality at the metal through manipulation of the relative reactivities of two diastereomers. Recent applications of MAP species to a variety of reactions catalyzed by alkylidene complexes, along with fundamental studies concerning metathesis at a stereogenic metal center, will be discussed.

Photonic Metamaterials, Nano-plasmonics and Superlens
Recent theory predicted a new class of meta structures made of engineered sub wavelength entities - meta "atoms" and "molecules" which enable the unprecedented electromagnetic properties that do not exist in the nature such as optical magnetism and artificial plasma. Especially, the predicted superlens made of metamterials breaks the fundamental diffraction limit, which may have profound impact in wide range of applications such as nano-scale imaging, nanolithography, and ultra-density data storage.

I'll discuss a few recent experiments that demonstrated these intriguing physics. We created the first bulk optical metamaterials that show the negative refractions. We demonstrated the unique superlens and hyperlens using carefully design of plasmonic materials dispersions. I will further discuss a new technology based on superlens for nano-scale lithography that may transform the next generation of nano-manufacturing, along with nano plasmonics for imaging and bio-sensing. The surface plasmon indeed promises an exciting engineering paradigm of "x-ray wavelength at optical frequency".

Nanobiophotonic Cellular Galaxy and Optogenetics for Quantitative Biology and Biomedical Innovations
Our understanding of biological systems is increasingly dependent on our ability to visualize and measure biomolecules and biological events with high spatial and temporal resolution in a living cell. Current fluorescence and confocal microscopy requires fluorescent labeling steps. The electron microscope (EM) can resolve subcellular structures without labeling, but EM imaging damages living cells. Moreover, fluorescence and EM microscopy cannot provide spectroscopic information (i.e. chemical fingerprints). Innovative nanoplasmonic local light sources and Plasmonic Resonance Energy Transfer (PRET) nanospectroscopy offer striking advantages over traditional molecular imaging techniques: stability, biocompatibility, selectivity, and spectroscopic imaging capability. By visualizing intracellular nanoplasmonic probes, we obtain snapshots of what we, metaphorically speaking, refer to as the Cellular Galaxy. By focusing on specific nanoplasmonic probes within this "galaxy" of probes, we can measure ultra-localized biochemical structural and kinetic features. In essence, the nanoplasmonic probes function as explorable "nano-satellites" in the living cellular environment.

We also have developed Oligonucleotides on a Nanoplasmonic Carrier Optical Switch (ONCOS) for the remote optical control of gene regulation and protein expression. The Optogenetic ONCOS allows on-demand gene silencing with nanometer-scale spatial resolution and localized temperature controls in living cells. The ONCOS and PRET are being applied for molecular/cellular diagnostics, therapeutic applications, and experimental system biology since these nanoplasmonic biophotonic devices will provide us precise spatial and temporal controls of gene interferences and spectroscopic information of living cellular mechanism. Bionanophotonic molecular ruler is also accomplished to measure the dynamics of DNA and protein interactions and understanding cellular dynamics. In-vivo Surface Enhanced Raman Spectroscopy (SERS) probes, in-vitro integrated nanofluidic SERS, and optofluidic ICs are developed for label-free molecular diagnostics and drug discovery. All these nanoplasmonic biophotonic devices can impact on optogenetics, medical diagnostics, and systems nanomedicine.

Metabolic Engineering: Enabling Technology for the Biological Production of Fuels and Chemicals
Metabolic engineering is a young field, just over 15 years old. During this period, it has developed a well-defined methodology and a focused research portfolio of rich intellectual content and particular relevance to biotechnology and biological engineering. Its goal is to harness the immense potential of microorganisms for the production of useful products, in particular from renewable resources. This it does by engineering the cellular metabolism such as to favor product-forming pathways while maintaining normal cellular functions. After many successful applications, Metabolic Engineering now needs to adapt itself to rapid changes whereby we have instead of too few genes lots and lots of genes and, instead of a handful of measurements, avalanches of data. Although the focus (e.g. improving cells) and main theme (e.g. assessing cell physiology) of metabolic engineering remain the same, new tools are required to take advantage of these developments. Such tools will come from a systemic view of cellular function and will strengthen the integrating and quantifying aspects that have given this field its unique identity.

In this talk we will review how metabolic engineering, as a field, helped crystallize these concepts along with the main challenges in aligning metabolic engineering with the goals and mind-frame of the new biology. New concepts of importance in the post-genomic era will be presented that allow the engineering of cells to elicit multigenic properties, a task difficult to achieve following the usual single gene paradigm. These ideas will be illustrated with examples from applications of Metabolic Engineering to the production of chemical products and biofuels from renewable resources.

Assemblymember Mike Feuer to Host Nanotechnology Summit at the CNSI
Assemblymember Mike Feuer (D-Los Angeles) in association with UCLA Office of the Vice Chancellor for Research and the California NanoSystems Institute (CNSI) present "The Future of Nanotechnology: Legislative Summit".

There are spaces in the world too small to be seen with even the most powerful optical microscopes. Nanotechnology, sometimes referred to as the science of the very small, has far-reaching economic and quality-of-life implications. How small is small? A nanometer is one-billionth of a meter. The human hair is approximately 80,000 nanometers wide, for example. A nanometer-sized particle also is smaller than a living cell and can be seen only with the most powerful microscopes available today. Numerous products featuring the unique properties of nanoscale materials - including computer equipment, drug delivery systems and medical diagnostic tools, burn and wound dressings in hospitals, car parts, protective coatings on eyeglasses, cosmetics and clothing - are available to consumers and industry today. And new uses in our homes, offices and on the road are being envisioned and developed. This summit is the first step for stakeholders from industry, government, research institutes and environmental groups to discuss responsible ways to regulate nanotechnology without stifling progress.

Panel 1: Environmental and Health Implications of Nanotechnology: Narrowing Our Knowledge Gap

Thermoelastic Dissipation as an Energy Loss Mechanism in Silicon Microelectromechanical Resonators
The silicon microelectromechanical systems (MEMS) resonator is poised to replace the quartz resonator as the device of choice for frequency references, which pervade most of the electronic devices currently being produced, with > 10 billion quartz timing crystals produced every year. Before silicon can overtake this industry, some critical technological challenges must be solved, namely stable packaging and optimization/understanding of energy dissipation of resonators.

One fundamental challenge for micro/nanoscale resonators is to understand the pathways by which they dissipate their vibrational energy. Even though these resonators have been in the research community for multiple decades and the underlying mechanisms of energy dissipation are fundamental physical phenomena (e.g., heat flow, phonon-phonon interactions, dissipation from chemical bonds on the resonator surface, elastic collisions with air molecules, energy loss from the resonator anchors), predictive models still do not exist for all types of energy dissipation. Without an understanding of these phenomena, it is impossible to predict the quality factor, a critical parameter, of a resonator.

One energy loss mechanism that becomes relevant at the micro/nanoscale is thermoelastic dissipation (TED), a phenomenon where energy is irrecoverably transferred from the mechanical to the thermal domain. Finite element simulations that capture the bi-directional coupled physics between mechanical and thermal domains were used to predict the TED-limited quality factor in MEMS resonators. Experimental validation was obtained by fabricating these devices within a novel single-wafer encapsulation technique. This encapsulation enabled reliable, repeatable measurement of devices and mitigation of other energy loss mechanisms, thereby isolating TED as the dominant energy loss mechanism. Based on these simulations, novel resonator geometries were designed, fabricated, and tested, demonstrating the ability to engineer the quality factor in MEMS resonators.

Virtual Surgery: Computational Methods and Simulations for Facial Reconstructions
This talk will cover a personal history of this surgeon who has attempted over the past thirty years to apply computer methods to the surgical care of patients with facial malformations. The Institute of Reconstructive Plastic Surgery at New York University Medical Center was the first center funded by the National Institutes of Health to study children with severe facial malformations. Evaluation of treatment outcomes required the development of statistical methods for the evaluation of smoothly curving three dimensional surfaces. This naturally led to numerical "error terms" when fitting a particular patient to normative models for the purposes of surgical simulation. As numerical surgical planning evolved, it became necessary to develop methods for delivering coordinated intraoperative precision. This led to the use of intraoperative vision systems and surgical robotics. Coincident with the craniofacial effort was an outreach program to repair cleft lip and palate in developing countries. Teaching the complex three dimensional movements required to achieve good results is difficult. We began using a three dimensional computer graphics animation program, Maya®, to describe these procedures. Later these procedures were abstracted into video game format to allow the student to explore these procedures in an interactive way.

The Speaker

Court Cutting is Professor of Plastic Surgery at New York University Medical Center. Over the past 20 years his surgical practice has been devoted to the care of children with facial malformations. Dr. Cutting has developed an intraoperative virtual reality system for the tracking and positioning of facial skeletal fragments. He began working with the Smile Train charity in 1999 to develop training tools to teach cleft lip and palate surgery to doctors in third world countries.

Understanding Human and Humanoid Motions and Emotions
The average age of the Japanese population is rising fast because of an increased life expectancy and a reduced birth rate. In this aging society, it is expected that there will be a growing need for home, medical and nursing care services, including those provided by robots, to assist the elderly both on the physical and the psychological levels. These new devices should be capable of smooth and natural adaptation and interaction with their partners and the environment, should be able to communicate naturally, and should never have a negative effect on humans, neither physical nor emotional. The concept behind all these devices is "partner". In particular, Partner Robots will act as human peers in everyday life and perform mental and communicational supports for humans as well as physical supports.

In this regard, human-robot communication and interaction (particularly in regard to the role of emotions) are extremely important, especially in the case of home and personal assistance for elderly and/or handicapped people. If a robot had a "mind" (intelligence, emotion, and will) similar to the human one, it would be much easier for the robot to adapt and interact with its human partners and the environment. Unfortunately, at present, we do not yet have sufficient knowledge and understanding of humans, and we do not know how to clearly define the criteria to evaluate these interactions.

To solve this problem, we should observe and analyze the human being, an extreme and exquisite example of robotic system. This could lead to the clarification of the basic mechanisms of the human neuromusculoskeletal system, and how its performance is related to emotional perception and expression. This, in turn, will be the core part of a huge range of extremely important applications involving the interactions between people and robots. The possible outcomes of this research for an aging society are tremendous.

The ultimate goal of these research activities is to provide the society with the tools necessary to improve and enhance the quality of life of elderly and disabled people: better health-care systems, human-support devices, teleoperation methods, and so on.

The unique properties of nanoscale materials offer excellent prospects for the monitoring biomolecular interactions and for designing novel bioelectronic devices exhibiting novel functions. This presentation will describe greatly amplified and multiplexed bioelectronic assays of DNA and proteins based on different biomaterial-nanomaterial assemblies. We will also discuss new nanowire-based machine-like operations ranging from delivery vehicles (and related self-powered nanomotors) to 'artificial-muscle' nanoactuators (based on electrical or magnetic stimuli). Finally, we will illustrate novel nanowire-based strategies for activating on-demand bioelectrocatalytic processes and bioelectronic devices, in general.

Expression Genetics and the Phenotype Revolution
Abstract:
The identification of disease genes associated with pervasive and common diseases such as cancer, heart disease, diabetes, neurodegeneration, and addiction can require huge population sizes. Massive projects of these types require extremely efficient phenotyping technologies. We have made enormous progress on the genotyping front, and it is now time to focus energy on devising ultrahigh-throughput methods to phenotype. Molecular phenotyping of the transcriptome has matured, and it is now possible to acquire more than 1 million mRNA microphenotypes. Proteomic and cell-based assays are also maturing rapidly. As I will review in this talk, rodent populations combined with massive phenome data sets and sophisticated bioinformatic data mining methods are essential to gauge our ability to predict susceptibility and disease outcome in human populations.

From Single to Assembled Chromophores
Abstract Description:
The study of individual chromophores, in particular porphyins and phthalocyanines, at a surface is of increasing interest due to the numerous foreseen applications in the area of nanotechnology. The development the of catalytic surfaces or spintronic arrays requires a precise control over the deposition and ordering of the molecules at the solid liquid interface. The self-assembly and self-ordering of such molecules at a surface is complex mechanism of multiple processes such as dewetting, supramolecular self-assemblyand many others which occur simultaneously. Once formed the investigation of the properties and behaviour of, individual chromophores or the formed arrays and their subsequent application as functional surfaces is also a non-trivial process.

The in-depth study of several systems ranging from monomeric to trimeric and polymeric systems and their self-assembled architectures has been carried out using SPM (scanning probe microscopy) and CFM (confocal fluorescence spectrsopytechniques at the liquid-solid interface. Using the former technique (STM) the catalytic cycle a single manganese porphyrin on a gold surface has been monitored during the conversion of an alkene to an epoxide using molecular oxygen (Nature Nanotechnology 2, 28 - 289 (2007)). Combining both above techniques the assembly of porphyrin trimers into a periodic array of micronmeter long nanowires at a surface has also been studied. By the precise design of the chromophoric building block, parallel m long consisting of millions of lines 5 nm thick, 100 molecules covering areas cm2, can be self-organized and the subsequent surface ultilized as a command layer for twisted nematic liquid crystal devices (Science (2006), 314(5804), 1433-143)).

In a finally assembly approach, polyisocyanide-molecules based m and wires can be synthesized, with lengths upto 15 molecular weights in excess of 20 million Daltons (see figure above). The investigation of the energy and electron transfer along these wires has led to there application in photovoltaic devices, (Angew. Chem. Int. Ed. 2004, 43, 4045 -4049; J. Phys. Chem. B 2006, 110, 7803-7812).

The motion of these chromophoric wires in a polymeric matrix has been observed using CFM, revealing the first example of reptation in a polymer matrix. The concept, synthesis and observations for these different chromophoric assemblies will be discussed.

Oligo(p-benzamide)s - Supramolecular Synthons for the Nanoscale Organization of Polymers
Coil-coil block copolymers and their solution and bulk structures have been studied in great detail. Amphiphilic coil-coil diblock copolymers typically form phase-separated morphologies with domain sizes between 10 nm and 100 nm.[1] One way to obtain smaller domain sizes is via rod-coil block copolymers in which a discrete oligomeric rod-block is attached to a polydisperse coil-block. This allows the generation of nanoscopic domain sizes on similar length scales as that of the oligomeric rod itself.

Such precisely defined oligomers can be synthesized and attached to polymeric coil blocks using the tools of classical multi-step organic synthesis. In recent years, this boundary between classical organic synthesis and polymer chemistry has been crossed by many groups aiming to create new block-copolymer architectures in which at least one block is precisely defined. [2]

Recently, we described the synthesis[3] and aggregation behavior[4,5] of a series of oligo(p-benzamide)-b-poly(ethylene glycol) monomethyl ethers in which strong directional hydrogen bonds are responsible for the formation of nanoscale solution structures. An overview of different synthetic strategies aiming at precisely defined oligo(p-benzamide) (OPBA) coil-block copolymers will be presented. The nanoscale aggregates formed by these polymers in non-polar solvents were analyzed using scanning probe microscopy (SPM), transmission electron microscopy (TEM) as well as light scattering techniques.

An overview of four different synthetic approaches to such polymer architectures is presented: a precursor route for synthesis on a soluble support (1), an iterative oligomer synthesis in solution (2), [6] a fully automated solid supported synthesis (3)[7,8] and an automated larger scale synthesis (4)[9] for supramolecular rod-coil copolymers are described. These four different synthetic routes allow the preparation of materials with varying degrees of precision, ranging from exact molecular weight and sequence control for the solid supported synthesis, to polydisperse materials for the automated lager scale synthesis.

Oligoaramide hetero-sequence design as a means to control shape, non-covalent interaction and hierarchical organization into nanostructures will be discussed.

"Nanoparticles and Nanomaterials in Aquatic Environments: Transport, Aggregation, and Environmental Implications"
Professor of Environmental and Chemical Engineering at Yale University will be the guest speaker for the MWH Distinguished Lecture in Environmental & Water Resources Engineering.

Naturally occurring nanoparticles are ubiquitous in aquatic systems. With the emergence of nanotechnology, engineered nanomaterials, such as fullerene and carbon nanotubes, will likewise find their way into natural waters. Understanding the aggregation behavior of these nanoparticles is important for predicting their transport, reactivity, and bioavailability in aquatic environments. This presentation will focus on the role of solution chemistry in the aggregation kinetics of iroiron oxide (hematite) and fullerene (C60) nanopatricles. The early stage aggregation kinetics of these nanoparticles have been investigated via time-resolved dynamic light scattering (DLS), under various solution chemistries (monovalent and divalent cations, and presence of polysaccharides and humic acid) Supported by TEM and AFM measurements, the mechanisms of nanoparticle aggregation are elucidated. In addition to the aggregation kinetics data, recent work on the interaction of carbon nanotubes with bacterial cells will be described.

Prof. Elimelech is the Roberto C. Goizueta Professor of Environmental and Chemical Engineering at Yale University. In 2006, he was elected to the National Academy of Engineering and in 2005 was awarded the Athalie Richardson Irvine Clarke Prize, perhaps the most prestigious award in the US for researchers in the water quality and water resources.

This event is presented by the UCLA Department of Civil & Environmental Engineering and the CNSI Nanotoxicology Seminar Series in conjunction with WMH.

Chemical and Electrochemical Properties of Endohedral and Multilayer Fullerenes
Trimetallic nitride endohedral fullerenes ( M3N@C2n, M=Sc, Y, Er, Gd, etc and n=34-44) were serendipitously discovered in 1999 and constitute a very interesting class of compounds. The interplay between the nature of the endohedral cluster and the exohedral chemical properties has turned out to be a rich field with unanticipated results. Reactions that work well on a given carbon cage (C80) with one metallic cluster completely fail when the metal is changed. Other reactions show different regiochemistry as a function of the encapsulated metal cluster. Somewhat surprisingly, different isomeric forms (for example, Ih and D5h symmetry Sc3N@C80 ) exhibit totally different redox properties and these have been used as the basis for a separation method. The redox of many of these compounds show irreversible behavior, but the detailed mechanisms are still not well understood, and probably involve EC processes within the carbon cage. Electrochemical and ESR results are somewhat contradictory but can be rationalized by invoking intracage chemical rearrangements.

Dr. Luis Echegoyen is the Division Director for NSF Chemistry (CHE). He joined the National Science Foundation from Clemson University where he served as Chair for the Department of Chemistry.

Nanotoxicology Seminar - "Assessing the Risks of Nanoparticles: The Fullerene Example"
Abstract:

Emerging technologies, including nanotechnologies, affect the social, economic, and environmental dimensions of our world, often in ways that are entirely unanticipated. There is considerable effort underway to explore uses of nanomaterials in applications such as membrane separations, catalysis, adsorption, and analysis with the goal of better protecting environmental quality. Along with the growth of a nanochemistry industry there is also the need to consider impacts of nanomaterials on environment and human health. Early work on nanomaterial exposure and toxicity has often focused on a relatively newly discovered allotrope of carbon referred to as fullerenes. Early data on potential fullerene exposure and toxicity are examined.

Hubris or Hybrids? On the Cultural Assessment of Nanotechnology
Guest Speaker: Professor Andrew Jamison, Technology, Environment, and Society from Aalborg University, Denmark

Abstract: As with many new technologies before they find their appropriate - and often inappropriate - uses in society the meanings of nanotechnology are still unclear. There is both a great deal of hype and a good deal of ignorance accompanying the emergence of this new field of research, and it can therefore be of some importance to attempt to provide a cultural assessment of nanotechnology. Drawing on a conceptual framework that he has developed with Mikael Hard in their recent book, Hubris and Hybrids. A Cultural History of Technology and Science (Routledge 2005), Andrew Jamison will discuss both the manifestations of hubris, as well as the processes of hybridization that will be necessary if nanotechnology is to have a meaningful presence in our societies. He will also present his own experiences bringing contextual knowledge into the education of nanoscientists and engineers as an example of hybridization.

"AFM Technology beyond Imaging: Applications towards Personalized Medical Diagnostics"
Abstract Description: Micro-fabricated silicon cantilevers arrays offer a novel label-free approach where ligand-receptor binding interactions occurring on the sensor generate nanomechanical signals like bending or a change in mass that is optically detected in-situ. We report the detection of multiple unlabelled biomolecules simultaneously down to picomolar concentrations within minutes. Differential measurements including reference cantilevers on an array of eight sensors enable sequence-specifically detection of unlabelled DNA and are suitable to detect specific gene fragments within a complete genome (gene fishing). Expression of detection of inducible genes and the detection of total RNA fragments in an unspecific background will be shown.

Ligand-receptor binding interactions, such as antigen recognition will be presented. Antibody activated cantilevers with sFv (single chain fragments) which bind to the indicator proteins show a significantly improved sensitivity which is comparable with SPR (Surface Plasmon Resonance).

In addition, this technology offers a broad variety of receptor molecules application such as e.g. membrane protein recognition, micro-organism detection, enantiomeric separation.

New coating procedures, enlargement of the active surface area by dendritic molecules as well as improvement of the receptor-cantilever chemical bond will be presented.

These new findings may lead to a novel individual diagnostic assay in a combined label-free GENOMICS and PROTEOMIC biomarker sensor (COMBIOSENS).

Nanostructure Processing of Advanced Catalysts and Biomaterials
Abstract Description:
Nanostructured materials are of interest for a variety of applications. This talk describes the synthesis and properties of two classes of nanostructured materials: nanoparticulate materials and nanoporous materials for catalytic and biomaterials applications. Nanoparticulate materials are made up of crystallites or particles of ~10 nm. They may be generated by various physical and chemical approaches with ultrahigh surface areas. Through controlled synthesis in reverse microemulsions, my laboratory has achieved complex oxide nanoparticles with ultrahigh thermal stability for the effective catalytic combustion of methane. This approach has also enabled us to derive polymeric nanoparticles for the glucose-sensitive delivery of insulin. Through chemical precipitation and additive dispersion, we have also attained nanocomposite systems as highly selective and sensitive semiconductor sensors, bioactive ceramic orthopedic implants, and efficient gene delivery vectors.

My laboratory is involved in the synthesis of novel nanoporous materials with tailored oxidation states, coordination chemistry and electronic structure. We have found that sol-gel processing can be combined with supramolecular templating agents in deriving well-defined mesoporous and microporous transition metal oxides (termed TMS). The compositional flexibility and pore size tailoring of the TMS molecular sieves open new possibilities for catalytic applications beyond the silicate-based zeolitic materials or mesoporous MCM-41. We have also attained mesocellular foams by using triblock copolymers and swelling agents in templating silicate precursors. These ultralarge-pore materials have been used to fixate organometallic ligands for the effective epoxidation, hydroxylation, Heck catalysis and asymmetric hydrogenation. The resulting heterogenized catalysts provide for excellent activity, enantioselectivity and reusability.

Hybrid Metal-Semiconductor Nanoparticles
Special Physical Chemistry Seminar Co-Hosted by CNSI

Guest Speaker: Professor Uri Banin, Institute of Chemistry & the Center for Nanoscience & Nanotechnology, The Hebrew University of Jerusalem

Abstract: An important frontier in nanocrystal synthesis is the growth of composites of different materials in the same nanostructure as means of increasing functionality. One particularly interesting combination of materials is that of a metal and semiconductor in the same nanoparticle where metal tips can provide anchor points for electrical connections and for self assembly.

We developed the growth of metal (Au) tips on the apexes of semiconductor (CdSe) rods, forming 'nano-dumbbells' (NDB's), via a simple chemical reaction. From the viewpoint of self-assembly they are equivalent to bi-functional molecules such as the di-thiols manifesting two sided chemical connectivity and the use of the tips for assembly is demonstrated. We also found that by increasing the concentration of gold in the reaction, rods with a metal tip on one side are formed. This process occurs by a unique ripening process as substantiated by experimental work and model calculations. The process leads to a transition from two to one sided growth.

Such systems manifest a unique model for a metal-semiconductor nanoscale junction. A fundamental and intriguing problem associated with such systems is the mechanical and electronic properties of the metal-SC nanojunctions. The electronic properties of metal-semiconductor nanojunctions were investigated by scanning tunneling spectroscopy of the gold-tipped CdSe rods and by electrostatic force microscopy. In STS sub-gap states at the metal-semiconductor interface were observed, while in EFM we see evidence for charge separation at the metal semiconductor interface.

CNSI Special Seminar: Photon Counting Microdetectors and Their Applications
Photon counting is the technique of choice for the ultimate sensitivity in optical signal measurements. Started and developed with photomultiplier tubes, it received new impulse from the introduction of microelectronic detectors, called Single-Photon avalanche Diodes SPAD.

They combine typical advantages of microelectronics (small size, high reliability, ruggedness and suitability to integrated systems) with improved basic performance (high photon detection efficiency, low dark-counting rate, picosecond photon-timing and high counting-rate capability).

The seminar will outline the evolution of SPAD devices and associated electronics and will illustrate some examples of recent applications, such as: analysis of DNA and proteins; single molecule spectroscopy; adaptive optics in modern telescopes; non-invasive testing of ULSI circuits.

Abstract: What have Norse mythology, Christian iconography, Shinto shrines, the Charing Cross Underground Station in London, and Ballantine's beer from New Jersey got in common? They all have a symbol which mathematicians, who are into knot theory, would call a "six-three-two," also known as the Borromean Rings (BRs). Their proliferation on crests and statues, commissioned by the Borromeo family in 15th Century Tuscany, sealed the BRs' etymological fate. In addition to the BRs having made cultural inroads into art, theology and heraldry, the 20th Century witnessed the emergence of this six-node, three-component link on to the scientific scene in particle physics and molecular biology. In his UCLA Science Faculty Research Colloquium, Stoddart will relate how chemistry has just started to get in on the act with molecular BRs these past couple of years. By employing chemical synthesis in an unconventional manner, he will trace how molecular BRs - a chemical Gordian knot - have become ten-a-penny overnight. The tale illustrates Noel Coward's much quoted words, "The secret of success is the capacity to survive failure."

What do Moore Hall, Haines Hall and the Powell Library on the UCLA Campus have in common? Their walls and floors and ceilings are plastered with "four-two-one" knots, also known as Solomon Knots (SKs). This four-noded, two-component link is believed to contain all the wisdom of King Solomon: many cultures, including Stoddart's very own Celtic one, have adopted this emblem to represent knowledge. He will relate how ploutering about with the recipe for making molecular BRs produces molecular SKs. Just how and why remains a mystery to be solved.

Ask Stoddart the question, what are these molecular BRs and SKs good for and the answer is he doesn't know yet. What he can claim, however, is that history has a habit of repeating itself. Some 18 years ago, his group made their first "two-two-one" knot, also known as a catenane, i.e., a two-node, two-component link. Bistable analogs, and close relatives of this mechanically interlocked molecular compound, wherein one of the two links - the one responsible for bistability - is broken and blocked at each end, provide access to nanometer-scale switches. In this simple molecular abacus, which is called a bistable rotaxane, the surviving link can be induced to move between two different stations, realizing the ON/OFF states of the switch in the appropriate device setting. By feats of engineering from the top down, these bottom-up assembled bistable rotaxanes have been used successfully to create molecular random access memory (RAM) at a density that is well beyond 2020 on the semiconductor industry's roadmap.

Fraser Stoddart is Director of the California NanoSystems Institute, Professor of Chemistry and Biochemistry, and holds UCLA's Fred Kavli Chair in Nanosystems Sciences. He is internationally renowned for his research in molecular electronics - using molecules on the nanoscale as switches in computers and other electronic devices - and artificial molecular machines - using linear motor-molecules in nanochemomechanical and nanoelectromechanical systems (NEMS). Fraser is a pioneer in the making and harnessing of the mechanical bond in chemistry. His Colloquium is titled "Science Engineered by Art."
