  • Radioactive material containing chitosan for inhibiting cancer and preparation method thereof
    Patent number: 8367811
    Abstract: A radioactive material containing chitosan for inhibiting cancer and a preparation method thereof are revealed. The adioactive material containing chitosan is formed by using SOCTA chelating agent to connect chitosan and radionuclides such as 188Re, and Tc-99m etc. The preparation method of the radioactive material containing chitosan includes the steps of: prepare SOCTA-Chitosan compound; and prepare M(radionuclide)-SOCTA-Chitosan compound. By biocompatibility and clotting in alkaline environment of human blood of chitosan, the radioactive material containing chitosan is injected into cancer and staying there for a long time so as to achieve effectively treatment.
