pH-sensitive sandwich poly(amino acid) micelles.

Abstract

summary Structurally well-defined ABC triblock copolymers with hydrophobic poly(l-alanine) as A block and hydrophilic poly(ethylene glycol) (PEG) as C block were designed to form ‘sandwich’ micelles. The B block is a pH-sensitive poly(amino acid) with amino or carboxyl side groups. As pH changes, the hydrophilicity of the middle layer of the micelles will… (More)
