Abstrakt: The widespread use of antibiotics often increases bacterial resistance. Herein, we reported a silver peroxide-incorporated carbon dots (defined as Ag 2 O 2 -CDs) with high photothermal conversion efficiency via in situ oxidation process. The prepared Ag 2 O 2 -CDs exhibited ultra-small size of 2.0 nm and hybrid phase structure. Meanwhile, the Ag 2 O 2 -CDs were of a similar optical performance comparing with traditional carbon dots (CDs). Importantly, the incorporation of Ag 2 O 2 into CDs significantly enhanced photothermal conversion efficiency from 3.8% to 28.5%. By combining silver ion toxicity and photothermal ablation, the Ag 2 O 2 -CDs were capable of destroying gram-positive and gram-negative bacterium effectively. These findings demonstrated that the Ag 2 O 2 -CDs could be served as a potential antibacterial agent for clinical applications.
