PVA-reinforced glutathione–Ag hydrogels and release of Ag nanoparticles and drugs by UV-triggered controllable disassembly

Macromolecular chains of PVA efficiently supported the three-dimensional network structure of GSH–Ag gels, remarkably improving their thermal stability and mechanical strength and the controllable release of Ag NPs and drugs through UV-triggered gradual disassembly of GSH–Ag.
