• 　At Narishima Laboratory, aiming at high functionality of metal-based and ceramic-based materials used in the living body, structure control focusing on light elements in titanium-titanium alloys and cobalt-chromium alloys, which are metal-based materials, ceramics-based materials We are conducting research on the synthesis of calcium phosphate, surface / interfacial anisotropy, and the compounding of these materials by coating. In-vivo evaluation is performed through joint research with the Graduate School of Dentistry, Graduate School of Pharmaceutical Sciences, Institute for Materials Research, and Institute for Materials Research. We are actively promoting it. For more information, here .
