TARGETED DELIVERY OF IMAGING PROBES FOR IN VIVO CELLULAR IMAGING

摘要

The present invention relates to imaging probes comprising immunoliposomes that encapsulate self-quenching concentrations of stable free radicals or high-relaxivity contrast agents, such as nitroxides or trityl radicals, wherein the immunoliposomes comprise a targeting ligand, positioned on the surface of the immunoliposomes and having affinity for targeted tissue.
