Quadruple thermo-photo-redox-responsive random copolypeptide nanogel and hydrogel

Quadruple stimuli-responsive random copolypeptide of poly(methoxydiethyleneglycol-L-glutamate)-co-poly(S-(o-nitrobenzyl)-L-cysteine) was synthesized by ring-opening copolymerization, simultaneously presenting thermo-photo-redox-responsive self-assembly behavior and forming nanogel and hydrogel in water.
