In vitro antibacterial performance of Ag/BMO nanozyme. 1064 nm laser: 1 W cm⁻² for 10 min, H₂O₂: 3 mM, Ag/BMO NPs: 200 μg mL⁻¹. If not otherwise specified, all NPs were dissolved in DI water for detection. a Plate photographs demonstrating the antibacterial activity of Ag/BMO NPs. b Corresponding quantitive survival ratio of MRSA in (a). c Bacteria viability by monitoring absorbance change at 600 nm (The concentration of NPs solution ranged from 0 to 1024 μg mL⁻¹). d CLSM images of MRSA stained by LIVE/DEAD dye following incubation with Ag/BMO NPs with or without NIR laser irradiation. (PI emits red fluorescence and SYTO9 emits green fluorescence). e, f Fluorescence images and the corresponding quantified analysis result using DCFH-DA fluorescent probe
