Self-Assembled Monolayers of Polypeptides on Gold and Graphite Surfaces
Abstract
The advent of complex, self-assembling organic systems has provided new avenues for the functional control of material properties at the nanometer length scale. Pursuant to the continued development of such materials we are investigating the fundamental physics of controlled, or directed, self-assembly of complex organic molecules on conducting and insulating inorganic substrates. Scanning tunneling microscopy (STM) and atomic force microscopy (AFM) are indispensable tools in the characterization of self-assembled monolayers, and this talk will discuss our approach to the study of such monolayers using these techniques. Preliminary experimental and theoretical results on the arrangement of polypeptides on graphite and gold surfaces are presented.
