Abstract

Provided herein are nanoparticle platforms and combinatorial drug delivery vehicles comprising gold nanoparticles with a plurality of thilolated hyperbranched dendrons conjugated to the nanoparticle surface. The thiolated hyperbranched dendrons comprise chemically-modifiable surface groups, functionalized interior groups and nano-cavities within the hyperbranched structure to which a variety of payload molecules may be conjugated, optionally via a linker. Payload molecules may comprise nucleic acids, anticancer drugs and small molecule inhibitors, optionally with, non-cytotoxic signaling agents, for example, fluoroscein isothiocyanate. Also provided are methods for delivering one or more therapeutic agents to a cell or tissue or for treating a pathophysiological condition in a subject by delivering the combinatorial drug delivery vehicles to a cell or tissue associated with the pathophysiological condition to facilitate internalization of the vehicle to effect treatment.
