Engineered self-assembly for ion channel protein-based molecular sensors

Mork Family Department of Chemical Engineering and Materials Science

Graduate Seminar
Engineered self-assembly for ion channel protein-based molecular sensorsDr. Noah MalmstadtPostdoctoral Scholar
University of California at Los AngelesAbstract
There has been much recent interest in using channel proteins as the basis of new
chemical detection technologies, including molecular sensing and single-molecule DNA
sequencing; these proteins are also important drug targets. Ion channel measurements are
performed by incorporating proteins into lipid bilayer membranes; however, these 5 nm-thick
membranes are fragile, short-lived, and labor-intensive to fabricate. These shortcomings
greatly limit the use of ion channel proteins in engineered devices.
We have developed two novel technologies that address these shortcomings: In the
first, we have encapsulated lipid bilayer membranes within a hydrogel network. This
encapsulation process, in which a hydrogel is polymerized in situ around a self-assembled
lipid bilayer, results in membranes that are robust to mechanical perturbation and that last
over ten times longer than the previous state of the art. Hydrogel-encapsulated membranes
can support extended measurements of ion channel proteins at the single-molecule level,
and have the potential to enable long-lived ion channel sensors in portable devices. Our
second novel technology is a microfluidic system for automated membrane fabrication and
measurement. This system controls and automates the process of membrane self-assembly
through material-driven solvent extraction from a multiphase droplet flow. Ion channel
proteins can be incorporated in these membranes and measured with single-molecule
resolution. This on-demand bilayer fabrication technology can form the basis of membrane
arrays for high throughput sensing for chemical detection as well as drug discovery and
screening. These technologies provide two complementary pathways to the development of
devices in which channel proteins serve as active nanoscale sensing elements.Friday, December 1, 2006

University of California, Los AngelesEngineering design is sometimes inspired by Nature. The natural world is filled with crystals, periodic structures that interact with electron waves. Drawing on this analogy, photonic crystals are artificial periodic structures that are intended for electromagnetic waves, instead. Such nano-photonic structures are now being designed and patterned into Silicon-on-Insulator (SOI) to provide for commercial nano-photonic integration, as a component part of conventional CMOS circuits.Further optical frequency miniaturization will take us toward nano-plasmonics, metallic-wired electrical circuits, running at optical frequencies. At lower frequencies, new electronic switching devices that have a sub-threshold slope steeper than kT/q are expected to emerge. The research of the next 10 years will answer what comes after the semiconductor roadmap.

Unraveling Bacterial Mn(II) Oxidation
Fri, Dec 01, 2006 @ 01:00 PM - 02:00 AM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speakers:Hope A. Johnson and Bradley M. TeboThe Scripps Research Institute
La Jolla, CAAbstract
It is important to understand the fundamental mechanism of bacterial manganese(II) oxidation because it plays a role in many biogeochemical cycles and can be utilized for bioremediation. Prior work with Mn(II)-oxidizing bacteria has suggested that Mn(II) oxidation involves a multicopper oxidase, but whether this enzyme directly catalyzes Mn(II) oxidation is unknown. For a clearer understanding of microbial Mn(II) oxidation, we have undertaken biochemical studies in the model marine -proteobacterium, Erythrobacter sp. strain SD21. In vitro experiments with this strain showed the Mn(II)-oxidizing activity to be protein dependent. The optimum pH for activity was 8.0 with a specific activity of 2.5 nmol/min/mg and a Km = 204 µM. The activity is soluble which may suggest a cytoplasmic or periplasmic protein. Mn(III) is an intermediate in the oxidation of Mn(II) and likely the primary product of enzymatic oxidation by this organism. The activity is stimulated by calcium, but is not stimulated by copper in vivo or in vitro. Surprisingly, the activity was enhanced by pyrroloquinoline quinone (PQQ) and NAD+. PQQ could also rescue Pseudomonas putida MnB1 non-Mn(II)-oxidizing mutants with insertions in the anthranilate synthase gene. Partially purified Mn(II) oxidase was significantly enriched in quinones and had a UV/VIS absorption spectrum similar to a known quinoprotein but not to known multicopper oxidases, suggesting that quinones may play an integral role in bacterial Mn(II) oxidation. In addition to investigating enzymes involved in Mn(II) oxidation in laboratory model strains, we have also assayed and directly identified enzymes from the environment.Location: Kaprielian Hall (KAP) - rielian Hall, Room 203

Water in Green Manufacturing: The Next Frontier
Fri, Dec 01, 2006 @ 01:00 PM - 02:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:Azita Yazdani, P.E.
President and CEO
Exergy Technologies Corporation
25 Mauchly, Suite 316, Irvine CA 92618
Phone: 949-231-1390
Fax: 949-757-2715Abstract:Water is the most important raw material in terms of quality and quantity used in many manufacturing processes. An average process bath is made of at least 80% water, followed by most process steps that use one or more water rinses. Water can solve and cause many problems in production. Manufacturing plants spend millions of dollar each year to remove impurities before the water used in their processes is acceptable for use. Additionally, water quality plays an important role in ensuring process performance and quality of product.Membrane technologies can play an important role in delivering acceptable water quality to many processes. Today, these technologies also show promise for recycle and reuse applications of both water and process chemicals. Various membrane and electro-membrane technologies can provide and maintain high quality water and chemicals for process applications. These technologies help companies reduce the cost and operational downtimes experienced by the manufacturing processes by making reuse and recycling cost effective.Location: Kaprielian Hall (KAP) - rielian Hall 156
