Muscle-inspired MXene/PVA hydrogel with high toughness and photothermal therapy for promoting bacteria-infected wound healing

were 98.3 and 95.5% respectively). In addition, it could effectively promote the proliferation of NIH-3T3 cells. In mouse wound models, the hydrogel was effective in inhibiting wound infection and promoting skin wound healing (the rate of wound closure was 98%). These results indicated that the MXene@PVA hydrogel, with high toughness and anisotropy properties, has the potential to be an excellent antibacterial wound healing dressing.
