Aa Digital photographs and b relative wound closure area, Ba representative colony formation assays of MRSA collected from the wound site on day 14, and b bacterial viability of MRSA until day 18 from the wounds untreated and treated with 3 M bandage and 50 µg mL⁻¹ (in terms of MXene) of Cu₂O/Ti₃C₂T_x nanosheets without and with NIR irradiation (808 nm, 0.54 W cm⁻², 10 min). The error bars b in A and B represent the standard deviation of three repeated measurements. C Histological analysis of tissue sections isolated on postoperative day 14 from the untreated and treated wounds. Red and yellow lines represent the thickness of the epidermis and dermis, respectively. Scale bar in A and C are 1 cm and 100 µm, respectively
