STIMULI-RESPONSIVE INTERPOLYMER COMPLEX COATED HOLLOW SILICA VESICLES

摘要

A porous hollow silica particle with an interpolymer complex immobilized thereon is provided. The interpolymer complex comprises a first polymer immobilized to a surface of the silica particle, and a second polymer complexed with the first polymer. Pharmaceutical compositions comprising the silica particle, and methods of forming the silica particle are also provided.
