| Research Abstract |
In this project, X-ray sensitizing material was developed for radiation therapy of cancer to reduce irradiation dose. Metal-bearing star polymer, which has many metals in its core, was prepared by living radical polymerization and was employed as an X-ray sensitizer. The obtained metal-bearing star polymer was added to HeLa cells and incubated. X-ray was then irradiated to the cells. More cells containing the star polymer were killed than that without the star polymer, which indicates that the metal-containing star polymer actually worked as an X-ray sensitizer.
