A dynamic nano-coordination protein hydrogel for photothermal treatment and repair of infected skin injury.

Abstract

In this work, a dynamic photothermal hydrogel based on copper disulfide nanoparticles and thiolated gelatin was reported. The resultant hydrogel enabled rapid photothermal sterilization and the sterilization rate could reach 99.9% after 10 minutes of near-infrared irradiation. In addition, the hydrogel exhibited typical dynamic properties with self-recovery, injectability and photothermal conversion ability, showing great potential as a highly adaptable and antibacterial wound dressing for infected tissue injuries.
