Polymer Self-Assembly

Self-assembled amphiphilic block copolymers have found widespread application in nanomedicine as potential vehicles for therapeutic and diagnostic agents. Amphiphilic block copolymers, like surfactants, are capable of self-assembling into a continuum of morphologies including spherical micelles, worm-like micelles, and vesicles. The resultant morphology depends on the packing of the block copolymer chains. Using controlled polymerization techniques, we synthesize stimuli-responsive block copolymers to investigate the effects of molecular weight, block length, polymer composition, chain architecture, and external stimuli on the resulting self-assembled morphology in solution.
