Zwitterionic amphiphilic homopolymer assemblies

Abstract

Zwitterionic amphiphilic homopolymers can be conveniently prepared in one-pot using activated ester-based polymer precursors. We show that these zwitterionic polymers can (i) spontaneously self-assemble to form micelle-like and inverse micelle-like assemblies depending on the solvent environment; (ii) act as hydrophilic and hydrophobic nanocontainers in apolar and polar solvents respectively; (iii) undergo pH-responsive surface charge and size variations; and (iv) exhibit the least cytotoxicity compared to the structurally analogous amphiphilic homopolymers.
