Fall 2013 Chemistry-Physics Seminar

Marc Knecht, associate professor of chemistry at the University of Miami, will present his research talk "Exploiting the Bio/Inorganic Interface to Control the Activity of Nanomaterials" at 12:30 p.m. Thursday, October 10, in Science Building 272. An abstract of his talk appears below.

Before his presentation, from 11:00 to 11:45 a.m., Knecht will converse with undergraduate and graduate students at Buffalo State regarding his experiences of scientist as a career. This private conversation will be held in Science and Math Complex 201. This seminar is sponsored by the Auxiliary Services Grant Allocation Committee, the Vice President for Student Affairs Office, and the Faculty-Student Association.

Abstract
Bio-inspired approaches represent emerging methods to fabricate inorganic materials with vast applications ranging from energy storage to catalysis. For many of these materials, phage display-isolated peptides are used to nucleate and grow the structures where peptides bind and passivate the nanomaterial surface. Based on these highly specific interactions, a unique biotic/abiotic interface is generated, which contributes to the activity of the final structure. Unfortunately, minimal information is currently available about this structural detail due to the lack of analytical methods that can accurately probe this level. To overcome this, we have begun to apply chemical approaches to observe changes in the activity of biomimetic nanostructures through modifications of the
