Abstract

Provided are targeted structure-specific particulate-based delivery systems comprising: a nanoparticle; a PEG polymer coating on the surface of the nanoparticle; a targeting moiety conjugated on a surface of the nanoparticle and configured to promote specific binding to a cell surface molecule expressed by a target cell; and a biologically active agent in or on the nanoparticle, wherein the biologically active agent is selected to enhance a desired response in a target cell intracellularly or extracellularly. Methods of treating a disease or disorder administering the delivery system are contemplated.
