Senior Investigators: Dennis E. Discher & Andrea Liu IRG Leaders; Paul A. Heiney, Randall D. Kamien, Michael L. Klein, Virgil Percec, Shu Yang IRG-2 will collaborate to synthesize sstrongi-flexible, functional cylinders composed of dendrimer-based polymers & self-assstrongbling block copolymers. The goal is to understand the interplay between soft structure & function and thereby develop cylinders whose meso-conformations can be controlled to generate mechanical motion and cylinders that can be arrayed as flow-responsive nano-reactors.
