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.
Claims27
A nanoshell, comprising:
- a star polymer occlusion complex comprising i) an amphiphilic unimolecular star polymer having a crosslinked polymer core covalently linked to 6 or more independent polymer arms, and ii) a cargo material occluded in the star polymer;
- and
- a shell comprising gold exterior to and in contact with a peripheral surface of the star polymer occlusion complex;
- wherein the crosslinked polymer core is a product of a vinyl polymerization and/or a ring opening polymerization.

A method, comprising:
- treating a star polymer occlusion complex with gold seeds, thereby forming a seeded occlusion complex, wherein the star polymer occlusion complex comprises an amphiphilic unimolecular star polymer and a cargo material occluded therein, the star polymer having a crosslinked polymer core covalently linked to 6 or more independent polymer arms;
- and
- depositing gold by electroless deposition on the seeded occlusion complex, thereby forming a nanoshell, wherein the nanoshell comprises a shell comprising gold exterior to and in contact with a peripheral surface of the star polymer occlusion complex;
- wherein the crosslinked polymer core is a product of a vinyl polymerization and/or a ring opening polymerization.
