Abstract
A nanoshell is disclosed, comprising a star polymer occlusion complex comprising i) an amphiphilic unimolecular star polymer having a crosslinked core covalently linked to 6 or more independent polymer arms, and ii) a cargo material occluded in the star polymer; and a shell comprising an inorganic material in contact with a peripheral surface of the star polymer occlusion complex.
