A lecture on Designer Materials by Self- and Directed Assembly: Photorheological Fluids, Magnetic Microchains and Hemostatic Dressings by Srinivasa R. Raghavan, professor of chemical and biomolecular engineering at the University of Maryland.

This talk will provide illustrative examples of Dr. Raghavan's work with self- and directed assembly. He has created assemblies that respond to stimuli such as temperature, pH or light; an example of the latter are photorheological fluids. He has also used microfluidic techniques to create magnetic microcapsules of biopolymers, which he has then linked into flexible microchains. He has also developed self-assembling biopolymers that have the ability to gel blood cells and thereby serve as effective hemostatic dressings for both military and civilian use.
