Hollow silver–gold alloy nanoparticles for enhanced photothermal/photodynamic synergetic therapy against bacterial infection and acceleration of wound healing

fluorescent probe DCFH-DA. Manipulated by near-infrared laser triggered mild hyperthermia and limited ROS amount, Ag@Au-Ce6 NPs could effectively kill bacteria that are free and colonized on the surface of wounded skin, promoting epithelium migration and vascularization, further accelerating wound healing, which showed great promise for biomedical application.
