sol-gel chemistry. Antibacterial nanorods of CQDs-ZnO had strong antibacterial activity under visible light irradiation, and a concentration of 0.1 mg/L was able to kill more than 96% of bacteria. The photocatalytic antibacterial mechanism was also studied. CQDs-ZnO produced more than three times the free radicals than pure ZnO under visible light irradiation. These free radicals destroyed the bacterial matrix of the cell wall and released cell proteins and nucleic acids. Moreover, CQDs-ZnO showed low cytotoxicity and can be used in medical applications.
