The Individual

ZnO/GQD nanocomposites exhibit markedly enhanced antimicrobial activity under UV photoirradiation as compared to that in ambient room light, due to photo-induced generation of reactive oxygen species. The activity of the nanocomposite is also higher than that with the individual components.
