Abstract
A discrete nanostructure formed by a method comprising providing an aliphatic multi-block copolymer. The aliphatic multi-block copolymer includes at least one polyester block and at least one functionalized polycarbonate block. The aliphatic multi-block copolymer, a deprotonating agent and water are mixed to form an aqueous mixture. The aqueous mixture is maintained at a reaction temperature suitable to result in self-assembly of the multi-block copolymer into nanoparticles.
