Associate Professor / Motohiro TAGAYA
Profesor TAGAYA integrates bioceramic research for the industry-academia fusion. He enjoys teaching his students how to proceed with research planning and preparation of nanobioceramics with enthusiasm and kindness. He always provides accurate advice and takes care of his students' careers.

Research Content

The purpose of our laboratory is to prepare nanobioceramics and design the interfaces towards “Cellular Therapeutics” in biomedical fields. We emphasize the technologies for artificially synthesizing and controlling nano-scale architectures based on nature phenomena in living organisms. The technology for skillfully combining inorganic and organic materials is very important for the nanostructural control. We have recently focused on the studies of “the nanobioceramic-induced control of cell functions through the interfacial material-cell interactions” and “the effective cellular uptakes of ligand-modified nanobioceramics”. In the future, these technologies can effectively encourage/improve the natural healing abilities of the patients.

A Day in the Lab

We carry out everything from material synthesis, characterization, analysis and evalution of cell growth. It is a heavy work but challenging and very rewarding. There is a friendly atmosphere where seniors and juniors can discuss and share research informtion without distintion. Since we are frequently talking with Prof. TAGAYA about research results and future plans, we can experiment at our own pace. There are many opportunities to present research results in academic conferences. Because the laboratory is equipped with biotecnology equipment for cell cultures, we clean laboratory every week in order to always study in a clean room.
