Best of both worlds: Diels–Alder chemistry towards fabrication of redox-responsive degradable hydrogels for protein release

Abstract

Poly(ethylene glycol)-based redox-responsive hydrogels have been prepared<italic>via</italic>the Diels–Alder reaction between a furan-containing hydrophilic copolymer and a disulfide-containing bis-maleimide based crosslinker.
