Excellent catalytic properties of luminescent Cu@CuS nanozymes and their antibacterial applications.

Luminescent Cu@CuS nanozymes have been prepared by a one-pot method, displaying high peroxidase-like and oxidase-like activity. Fluorescence images show that these nanozymes adhere to the surface of the bacterial cell and scanning electron microscopy reveals that the nanomaterials cause folding and collapse of the bacterial surface, resulting in bacterial death.
