| Outline of Final Research Achievements |
Neutron capture therapy (NCT) is one of available ways for intractable cancers in human body. BNCT is in practical use, in addition, gadolinium neutron capture therapy (GdNCT) is also useful because Gd ion has a toxicity against human calls by gamma-ray generation under irradiation thermal neutrons. Using a lanthanide phosphor including Gd synthesized by our technique, the phosphors are able to form unique shapes such as hollow sphere, and the phosphor showing a good emission can be used as a new type drug delivery system (DDS) possessing several functions such as gamma-ray generation under irradiation of thermal neutron, drug delivery and lavel of the tumor cells in one material. In this study, the preparation of hollow sphere lanthanide phosphor was performed using polymer beads as a template by hydrothermal treatment. And then the tumor cell killing effect of this material against cultured the cancer cell after irradiation of thermal neutron and incubation was investigated.
