Preparation of an amphipathic polymer library in a mixture of water/ethanol by photoinduced polymerization and evaluation of the cryoprotective activity

Abstract

Synthetic cryoprotectants with macromolecular structures are desirable as alternatives to commonly used ones. Herein, we prepared an amphipathic polymer library and evaluated the cryoprotective ability of the polymers by facile screening using red blood cells. The cryoprotective properties of the amphipathic polymers was independent of both the log P values of the hydrophobic groups and the ice recrystallization inhibition activity.
