A gold nanoparticle-based photothermal hydrogel assisted by an N-halamine polymer for bacteria-infected skin wound healing

antibacterial capacity under near-infrared (NIR) laser irradiation through the synergistic action of photothermal therapy (PTT) and chemical release therapy. It also showed an excellent ability to eliminate bacterial infection and promote wound healing, indicating that the pAMPS-Cl/AuNR@HA-DA composite hydrogel could be a promising dressing for the treatment of skin wounds.
