“Surface Chemistry of Gold Nanorods: Wrapping, Stitching, Exchanging and Coating”
Abstract:
Gold nanorods have potential applications as chemical sensing, biological imaging, and photothermal therapeutics. Our laboratory has developed the syntheses of these materials, in controlled size and shape, over the last few years. Surface modification of these nanomaterials is a key step to enable applications. In this talk I will describe our recent efforts to wrap up nanorods with layer-by-layer polyelectrolyte deposition in aqueous solution, in a way that allows for “capture coating” of small molecules at defined distances from the surface; how we can “fix” the surface of the nanomaterials by on-particle polymerization reactions; and how surface ligand exchange and overcoating affects biological properties of these materials.
Bio:
Professor Catherine J. Murphy is the Peter C. and Gretchen Miller Professor of Chemistry at the University of Illinois at Urbana-Champaign. She received two B.S. degrees, one in chemistry and one in biochemistry, from the University of Illinois in 1986. Professor Murphy received her Ph.D. from the University of Wisconsin in 1990. From 1990-1993, she was first an NSF and then an NIH postdoctoral fellow at the California Institute of Technology. From 1993-2009 Professor Murphy was a faculty member in the Department of Chemistry and Biochemistry at the University of South Carolina. In August 2009 she joined the faculty of the Department of Chemistry at the University of Illinois. Dr. Murphy has published nearly 200 peer-reviewed journal articles and has received numerous awards for research, teaching and professional service.
