Abstract

The present disclosure pertains to systems for forming hydrogel compositions that comprise a reactive polymer comprising a plurality of hydrophilic polymer segments and a plurality of first reactive moieties and gold nanoparticles, wherein the system is configured to deliver the reactive polymer and the gold nanoparticles under conditions such that covalent crosslinks are formed between the reactive polymer and the gold nanoparticles. The present disclosure also pertains to methods of treatment that comprise administering to a subject a mixture that comprises a reactive polymer comprising a plurality of hydrophilic polymer segments and a plurality of first reactive moieties and gold nanoparticles, under conditions such that the reactive polymer and the gold nanoparticles crosslink after administration, and to radiopaque crosslinked hydrogel compositions that comprise a crosslinked reaction product of a reactive polymer comprising a plurality of hydrophilic polymer segments and a plurality of first reactive moieties and gold nanoparticles.
