Research Theme of Active matter lab
“Active matter” is a substance that has a mechanism that converts the energy stored in chemical substances and light into mechanical work. It has characteristics not found in existing materials in that it spontaneously expresses movement.
We would like to pursue the scientific theory related to such active matter and create new materials based on it to eventually unveil the mystery of life!
