Key Points

To develop a composite photothermal polyacrylamide hydrogel loaded with Prussian blue and tannic acid to achieve controllable drug release, prevent collateral thermal injury, and accelerate the healing of infected skin wounds.
Synthesized polyacrylamide hydrogels loaded with Prussian blue and tannic acid, characterizing swelling behavior, microstructure, photothermal conversion, and light-triggered drug release.
Assessed in vitro cytocompatibility and antibacterial efficacy, followed by in vivo evaluation of infectious skin defect closure, bacterial clearance, and histological recovery in Sprague-Dawley rats.
The hydrogel achieved up to 600% swelling capacity with a highly porous structure, good light transmittance, and strong tissue adhesion.
Light activation provided photothermally switched, on-demand tannic acid release, demonstrating synergistic antibacterial efficacy while mitigating excessive heat damage to host tissue.
In vivo treatments in Sprague-Dawley rats confirmed enhanced biocompatibility, substantial bacterial suppression, and accelerated wound closure and re-epithelialization.
