Description

General description

Poly(ethylene glycol)-b-poly(N-isopropylacrylamide) (PEG110-b-PNIPAM44) undergoes thermoresponsive micellization in water, forming micelles of varied size, structure and distribution depending on the concentration of the block copolymer.

Application

Well-defined PEG-block-PNIPAM diblock copolymers can form thermoresponsive vesicles in water and enable controlled drug release.
