Gold nanoplates with superb photothermal efficiency and peroxidase-like activity for rapid and synergistic antibacterial therapy.

Gold nanoplates (AuNPTs) exhibit outstanding photothermal conversion efficiency (68.5%) and peroxidase-like activity. The combination of the very low H2O2 concentration (0.1 mM) and the low AuNPT dosage (50 μg mL-1) with 808 nm laser irradiation (1 W cm-2, 3 min) shows excellent synergistic antibacterial ability and healing of MRSA-infected wounds in vivo.
