Extending the utility of poly(N-isopropylacrylamide (PNIPAAm) hydrogels as robust cell-releasing materials for a self-cleaning biosensor membranes requires enhancement of both mechanical properties as well as swelling. In this study, we introduce electrostatic repulsive forces to the PNIPAAm hydrogel network by incorporating 2-acrylamido-2-methylpropanesulfonic acid (AMPS) into the 1st network to achieve enhanced mechanical properties as well as deswelling/reswelling kinetics.
