“Development of new process and its evaluation for biomedical materials based on physical chemistry”

Our research group focuses on the use of metallic biomaterials such as Ti alloys, NiTi, Co-Cr alloys, and Mg alloys in biomedical implants. It is predicted that the number of patients suffering from falls and deterioration of body functions will increase in today’s super-aged society. As a result, the demand is increasing for high-performance and inexpensive devices for reconstructing the body function. Metals are candidate materials of implants; in fact, 80% of the implants are made of metals. Therefore, our group is working toward developing “new-generation metallic biomaterials” and “novel processing methods” to fabricate and modify them from the viewpoint of their surface modification and composition/microstructure control. Some of the research studies are conducted under close cooperation with Institute of Development, Aging and Cancer, Tohoku University, Graduate School of Dentistry, Tohoku University, and a few private companies.
