Overview of Research

Our group develops material platform that brings out the mechanical function of polymer gel by tailoring polymer network design based on precise synthesis of polymers (ATRP, RAFT polymerization etc.) and solvent engineering. We aim at realizing a new type of scaffold material that leads to the fate of cell, by desingning structure and dynamics in nano-scale synchronized with macroscopic mechanical properties of soft matter.

The actors who stand on the stage of “polymer gel” are “polymer network” and “liquid” that swells it. On this stage, “polymer network” has been the main role for a long time. However, when we spotlight the “liquid” that is always devoted to bi-players, I expect that the new world of soft matter immediately open up. Why don’t we change the world with our soft matter?
