| Outline of Final Research Achievements |
Cryopreservation of cells is one of important technologies for regenerative medicine. Here, we focus on the interaction between polyampholytes and lipid membranes to clarify the mechanism of cell freezing and develop new materials. We found the improvement of cryoprotective function by introducing hydrophobic moiety into a polyampholyte, phase diagram of the polymer, adsorption behavior of the polymer on the membrane, and electrostatic effects on membrane structures.
