The invention uses iodixanol and ethylenediamine as raw materials, and a one-step hydrothermal method synthesizes carbon dots containing both nitrogen and iodine. On the surface of biologically compatible chitosan molecules, the formed complex is mixed with hydrogen peroxide as a new type of antibacterial agent, using carbon dot nanozymes to coexist with hydrogen peroxide. The oxidative activity of nanozymes promotes the oxidation process of bacterial cells and the consumption of antioxidant biomolecules, resulting in Oxygen products including H2O2 and other antibacterial activities from the accumulation of reactive oxygen species (ROS ) were reduced, while chitosan also had better antibacterial properties, resulting in a synergistic antibacterial effect. Mixed with ink, it is used for antibacterial of cigarette tipping paper. Its antibacterial properties meet the requirements of the tobacco industry, and it is a safe, environmentally friendly and effective new antibacterial agent. |
