In addition, antibiotics are mainly used for resisting bacteria at present, however, the abuse of a large amount of antibiotic drugs can cause the bacteria to generate drug resistance so as not to be completely eradicated, and further, the body is infected secondarily and serious side effects are caused. Therefore, it is important to find new, safe and effective anticancer and anti-infection methods.

Research shows that a large number of gas-phase active particles generated by the discharge plasma generate liquid-phase active oxygen ROS such as H2O2 and liquid-phase active nitrogen RNS such as NO 3-NO 2-in water through a series of physical and chemical reactions; in addition, Cl-in the sodium chloride aqueous solution can be converted into an active chlorine component RCS after plasma discharge treatment, and the sodium chloride aqueous solution has strong oxidizing capability. After the liquid-phase active particles act on cancer cells, the active oxygen level in the cells is increased, so that the oxidative stress on the cells is increased, and the apoptosis signal path of the cells is further activated to cause the cancer cells to die; on the other hand, the oxidizing ability of ROS and RCS in liquid phase can induce oxidative stress in cells, destroy the integrity of cell membranes and intracellular osmotic pressure, and alter the surface structure and chemical state of bacteria, thereby leading to bacterial death. Has great application prospect in cancer treatment and anti-infection.
