Polyarginine segments in block copolypeptides drive both vesicular assembly and intracellular delivery

Eric P. Holowka , Victor Z. Sun , Daniel T. Kamei & Timothy J. Deming

Polymeric vesicles are a relatively new class of nanoscale self-assembled materials that show great promise as robust encapsulants. Compared with liposomes, use of polymeric building blocks for membrane formation allows increased stability, stimuli responsiveness and chemical diversity, which may prove advantageous for drug-delivery applications|[nbsp]|.
