A hydrogel prepared by in situ cross-linking of a thiol-containing poly(ethylene glycol)-based copolymer: a new biomaterial for protein drug delivery.


A new poly(ethylene glycol)-based copolymer containing multiple thiol (-SH) groups was cross-linked in situ to form a polymer hydrogel under mild conditions. No organic solvent, elevated temperature, or harsh pH is required in the formulation or patient administration processes, making it particularly useful for delivery of fragile therapeutics, such as… (More)
