Outline of Final Research Achievements

Application of radionuclide-carrying liposomes to radionuclide therapy for cancer is promising as liposomes are able to deliver large amount of radionuclides to the tumor. However, radionuclides also accumulate in normal tissues such as the liver non-specifically, and cause abdominal radiation exposure. In this study, we devised a strategy whereby radionuclides with the property of metal ions and various chelating ligands to them were encapsulated in liposomes to promote the radionuclide clearance from the normal tissues.
