Professor Evgeny Katz Initiates Novel Biocomputing Project

A novel research direction related to mimicking computing operations by using biomolecular systems was recently initiated by Professor Evgeny Katz (the Milton Kerker Chaired Professor in Colloid Science at Clarkson University) and his group. Biomolecular systems based on natural enzymes can perform logic operations mimicking electronic logic gates. Individual enzyme-based logic gates were assembled and scaled up to biomolecular computing network systems performing various logic operations, such as mimicking a keypad lock security system. See picture. The biomolecular logic gates were associated with electronic transducers, and input signals of a different physical and chemical nature were applied to activate them. This research direction has been recognized by the NSF as a Grand Challenge for future studies during the next ten to fifteen years. The biocomputing research being carried out at Clarkson is currently supported by two NSF-sponsored grants. This multi-disciplinary research in biocomputing includes the collaborative efforts of several groups led by Professors Katz, Minko and Privman. Results of this work have already been published in high ranking journals, such as Journal of the American Chemical Society, ChemBioChem and Electroanalysis.

 

Clarkson University’s Professor Sergiy Minko Featured in ACS Nano Podcast

Professor Sergiy Minko (the Egon Matijevic' Chaired Professor of Chemistry)

An interview with Dr. Sergiy Minko, the Egon Matijevic' Chaired Professor of Chemistry at Clarkson University, was featured in the January ACS Nano podcast. His interview was about a paper that he coauthored with Research Professor Mikhail Motornov, graduate student Roman Sheparovych and Professor Evgeny Katz. This paper is titled "Chemical Gating with Nanostructured Responsive Polymer Brushes: Mixed Brush versus Homopolymer Brush," and was published in the January edition of ACS Nano. ACS Nano is an international forum for comprehensive articles on synthesis, assembly, characterization, theory, and simulation of nanostructures, nanobiotechnology, nanofabrication, methods and tools for nanoscience and nanotechnology, and self- and directed-assembly. The journal serves researchers at the interfaces of chemistry, biology, materials science, physics, and engineering.  

Minko’s podcast (Episode 6) can be heard on the Web at http://pubs.acs.org/journals/ancac3/podcasts

Professor Minko's research and expertise in materials science focus on the areas of smart/responsive polymer materials, smart colloids, nanostructured thin polymer films, formation of nanowires and nanoparticles, adhesion, wetting, adsorption regulations, and single molecule devices.
