Abstract
A platform technology provides particle and nucleic acid conjugates, and compositions thereof, with enhanced targeting to cells, tissues, organs. The particles and nucleic acids and other deliverables contain a synthetic binding protein such as a polypeptide monobody covalently conjugated to the surface of the particle or the nucleic acid, for linking a targeting agent to the particle's surface or the nucleic acid. The particles and nucleic acids and other deliverables optionally contain an antibody non-covalently conjugated to the binding protein, via an Fc domain of the antibody. The particles can include therapeutic agents, diagnostic agents, prophylactic agents, or a combination thereof, to be delivered to desired cells, tissues, and/or organs. The particles and nucleic acids and other deliverables can be used in a wide array of applications including, but not limited to, ex vivo perfusion of mammalian organs and in vivo disease treatment.
