We are conducting research using coordination chemistry techniques to create novel substances with unprecedented functionalities based on metal complexes. A metal complex is a compound in which a metal ion (such as copper or iron) forms strong bonds with surrounding molecules, known as ligands.
In metal complexes, the metal ion and ligands bind together in specific arrangements or shapes, forming a stable structure as a unified compound. Through these interactions, metal complexes can exhibit new functional properties that were not observed in the individual metal ions.
Recently, we have been synthesizing porphyrin derivatives containing metal ions at their centers and using these complexes as catalysts to explore oxidation reactions using only oxygen molecules from the air and light.

We have developed a novel surface coating material called CAT that could induce cell self-assembling （Japanese patent No. 5746240, No. 6704197）. The single cell aggregate was formed by self-assembly of all cells adhered on CAT coated area. This technology enabled us to obtain 3D cell constructs having desired shapes and sizes automatically by only seeding cells on CAT printed culture dishes, which have great application potential for regenerative medicine, artificial organs and drug discovery as 3D tissue preparation tools.

While using mechanical engineering (fluid dynamics, thermal engineering), applied physics (magneto science), and econometrics, I am conducting research on material informatics that integrates engineering and informatics. Practically, I analyze medical data using the methods of data mining and multivariate analysis. In the field of magneto science, I progress a technology called a “magnetic force booster” and succeeded in realizing a completely containerless protein crystal growth (see the photos). By the use of a magnetic levitation technique, I have also established in measuring the thermal properties of protein crystals.

I am studying the various phenomena which happen when accelerating an electric charge particle of monoatomic ion, a molecule ion and a cluster ion and irradiating the solid.
A target in our laboratory is to develop all kinds of computer simulation cords about the interaction between the ion and the solid, and to do an analysis of a phenomenon and a guess in the several fields of the ion engineering.
