Hollow biodegradable nanospheres and nanoshells for delivery of therapeutic and/or imaging molecules

摘要

A polymeric hollow nanoshell or nanosphere for release of an agent is described, wherein the hollow nanosphere comprises at least one biodegradable polymer, characterized in that the polymer is cross-linked. The biodegradable mono-disperse nanospheres described are suitable for use as carriers of biomolecules, therapeutic agents and/or imaging agents.
