Abstract

The subject invention provides a novel class of mixed-metal chalcogenide compounds exhibiting POD-like catalytic activity, efficient photothermal conversion under NIR irradiation, and broad-spectrum antimicrobial properties. The invention further provides hydrogel formulations incorporating these compounds in a polymeric matrix, as well as their use in a range of biomedical applications, such as treating infected wounds, preventing surgical site infections, and delivering localized, non-antibiotic antimicrobial therapy.
