The institute's demonstrated ability to attract stellar faculty and top tier students will have a critical impact on the development of the next generation of scientists, engineers, and artists, who will bring prosperity and enlightenment to the State of California.
To support the research, the CNSI encompasses eight core facilities which include both wet and dry laboratories, equipment in the form of electron microscopes, atomic force microscopes, X-ray diffractometers, optical microscopies and spectroscopies, high throughput robotics and class 100 and 1000 clean rooms for projects led by CNSI and other faculty. Each of the following core facilities will afford critical work space for numerous research projects led by CNSI and other faculty and will be available to industry and academia.
Advanced Light Microscopy / Spectroscopy
Shimon Weiss, Faculty Director
Laurent A. Bentolila, Scientific Director
The accelerating field of molecular imaging has witnessed major technical advances that are now introducing the cell biologist and the physician alike to a new, dynamic, subcellular world where genes and gene products can be visualized to interact in space and time and in health and disease. The mission of the Advanced Light Microscopy/Spectroscopy Shared Facility is to provide consultation, services and support for the application of novel spectroscopic methods and advanced image analysis techniques for the study of macromolecules, cellular dynamics and nano-scale characterization of bio-materials.
Our research resource is much more than just a state-of-the-art facility, since we provide both new imaging agents and new instrumental technologies.
Firstly, our facility support the development of novel imaging reagents and indicator probes made of inorganic fluorescent semiconductor crystals (known as quantum dots) that can be synthesized in various colors and functionalized with various biological molecules including nucleic acids, proteins, peptides, small compounds etc... The unique optical properties of qdots enable to multiplex many different biological signals in complex environments such as the living cell. Importantly, qdot imaging has the potential of covering all length scales (from the macro-, micro- to the nano-scales), which is a formidable asset to tackle the complexities and the dynamics of the various molecular and cellular events by probing when and where defined molecules appear, interact, and disappear.
Secondly, our facility provides a collection of high-hand, customized biological fluorescence microscopes and small-animal imaging devices that provide the ability to study these processes with high spatial and temporal resolution in whole organisms and in living cells down to the single molecule detection level with nanometer-accuracy.
Located on the second floor of the CNSI building, an optical suite of 1,000 square feet was specifically designed to house our microscopes with the required environment control (low vibration, air-filtered, air-conditioned to +1oC and light-tight) and services. The facility currently provides: Wide-field Fluorescence Imaging Microscopy, Iterative Deconvolution and Computational Derived Optical Sections, Confocal One-Photon and Two-Photon Laser Scanning Microscopy Imaging, Fluorescence Correlation Spectroscopy (FCS), Total Internal Reflection Fluorescence (TIRF) Microscopy, Fluorescence Resonance Energy Transfer (FRET), Fluorescence Lifetime Imaging (FLIM), Time-Correlated-Single-Photon-Counting (TCSPC) and Near-Infrared (NIR) Detection.

Bioscience Synthetic Chemistry Core Facility (BSCCF)
Mike Jung, Faculty Director
The Bioscience Synthetic Chemistry Core Facility (BSCCF) provides a dedicated laboratory for the synthesis of small organic molecules to aid bioscience research. Although high throughput screening enables the discovery of molecules with high medicinal potential, or hits, it does not render them in a viable form. The BSCCF is capable of rapidly transforming these hits into usable biological tools. The facility operates in tandem with the Molecular Screening Shared Resources (MSSR) core facility at CNSI, a high throughput facility. With the BSCCF's ability to design and prepare molecules for the testing of biological principles, which can only be done through chemical synthesis, this innovative facility, working with diverse scientific disciplines, is at the forefront of modern bioscience.
When a request for the synthesis of known compounds or analogues of screening hits is submitted by a bioscientist; this request is analyzed by Dr. Michael Jung, the facility director, in coordination with the bioscientist; the design of a synthetic protocol is generated; and lastly an assessment of the feasibility, estimated time and cost is made. Based on the outcome of those discussions about what the high-throughput hits mean and how good they are in terms of drug potential (especially likely non-selective toxicity), a decision is made on how exactly to proceed. Namely whether a synthetic project should be started within the core facility or whether it is better to follow another path, e.g., purchase library compounds, write a grant for support, hire an outside company, and questions of patents and startup opportunities.
At that point, the bioscientist has the option of continuing the collaboration, namely agreeing to the costs and time limitations of the project, which vary widely depending on the structures of the compounds desired, the number of analogues and the amount of materials needed. This initial assessment usually takes only a few days. Once a project is started, the compounds are designed, synthesized and purified by Dr. Xiaolu Cai, a skilled synthetic chemist with significant experience in synthetic chemistry and drug discovery.
UCLA is one of the preeminent institutions in the world for bioscience research and the BSCCF provides bioscience researchers with the synthesis of small organic molecules which are critical to their research work. The facility has the necessary capabilities to perform synthesis rapidly, on request and in-house, saving valuable research time and perhaps leading to drug discovery. The facility provides convenient access to readily usable molecules for the advancement of biology and research aimed at treating human diseases in the 21st century.

Integrated Systems Nanofabrication Cleanroom (ISNC)
Aydogan Ozcan, Faculty Director
Adam Stieg, Interim Technical Director
The CNSI Integrated Systems Nanofabrication Cleanroom (ISNC) consists of 8,900 square feet of vertical-flow clean room space and 680 square feet of class 10,000 support space. The clean room is divided into 12 process bays and their associated air return chases. There are 4 class 100 bays (3 of which have yellow lights for lithography applications) and 8 class 1,000 bays, 2 of which form a biology suite with its own dedicated air flow system. A full complement of utilities including high purity DI water, high purity nitrogen, reactive gases, chilled water etc. are available to each process bay. The latest advances in vibration isolation and electromagnetic shielding are integrated into the clean space to allow installation of the most sensitive and demanding fabrication and analysis equipment. The layout and wall structure allow for quick change of equipment with minimum impact to the clean room.
The ISNC approach to nanofabrication is unique in that it will integrate classic semiconductor tools and processes with biological, chemical, and medical substrates to extend beyond more traditional nano-device fabrication such as integrated circuits, quantum dots, single electron transistors, nanotips etc. toward DNA, single molecules, proteins and a host of other biologically relevant nanosystems. Traditionally, semiconductor processing excludes these types of applications because of the possibility of cross-contamination and equipment damage. By proper process design and equipment selection, the ISNC provides the opportunity to successfully join standard process techniques with evolving bio-medical and nanoscale fabrication applications. Integrating the biology suite into the clean room allows scientists to keep their samples free of even trace contamination which may affect the outcome of their experiments.
The ISNC uses the Core Lab Management System (CLMS), a centralized account management system. Information on how to become a new User can be found here.

Molecular Screening Shared Resource (MSSR)
Ken Bradley, Faculty Director
Robert Damoiseaux, Scientific Director
High-throughput screening (HTS) involves assaying a large number of unique molecules in order to identify those that have a specific biological or chemical function. Pharmaceutical and biotech companies have traditionally performed the lion's share of HTS. However, having so much of our screening capacity outside the academic and public research community, and having that capacity narrowly focused on drug discovery, restricts both the pace of basic science as well as its translation into improved health.
Thus, the establishment of academic HTS centers will serve the long-term goals of basic science and health research by providing a much broader range of screens than commercial firms typically undertake. Toward this end, UCLA has established the Molecular Screening Shared Resource (MSSR) to provide HTS capabilities to the academic community. Through close collaborations between physicians, biologists, and chemists, it is our goal to identify molecules with novel functions in basic cellular and molecular biology, and to develop probes and research tools whose uses include but are not limited to direct drug discovery.
In addition, these efforts will gain leverage from the California NanoSystems Institute (CNSI), as we incorporate new nanotechnologies into the screening process in order to advance miniaturization, improve throughput and reduce costs.

Nano and Pico Characterization
James Gimzewski, Faculty Director
Adam Stieg, Scientific Director
The Nano and Pico Characterization Lab (NPC) at CNSI provides access to state-of-the-art methods toward the characterization of surfaces, adsorbates, nanostructures, and devices through the use of Scanning Probe Microscopy (SPM).
SPM methods differ from conventional microscopes that use light or beams of charged particles in that the SPM probe is a mechanical object. These systems rely upon a unique, tactile sensing of interactions between sharp probe tips and a sample surface in a similar fashion to that used by a
visually impaired person reading Braille. The tiny fingers used in SPM terminate in a tip apex reduced by a factor of approximately 10 million times compared that of your finger.
Since SPM systems directly interact with the material of interest, they are also able to go beyond imaging and probe local physiochemical properties such as friction, adhesion, stiffness/modulus, electrical charge and local magnetism. As a result SPM encompasses a wide variety of underlying
techniques typically based on the fundamental methods of Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM).
STM relies on quantum mechanics to sense a tiny electrical current flowing between the tip and surface, which are not in contact. The overlap of the electron "clouds" of atom and specimen also permits the precise control of individual atoms and molecules in fabrication of nanostructures. This
element of control can be thought of as the ultimate limit of fabrication.
Atomic Force Microscopy relies upon sensing tiny forces between the tip and object in order to feel and visualize nanostructures. The method uses a soft spring made from a silicon micromechanical cantilever onto which a sharp tip is attached.
SPM systems in the NPC Lab operate in a diverse range of environments, including the extreme vacuum of space (UHV), atmospheric conditions and even in liquid (including biofluids and electrochemical environments). The CNSI Nano and Pico Characterization core facility encompasses SPM imaging under all these environmental conditions. It is therefore a cornerstone for developing new nanotechnology products and performing nanoscience research.
