Silver ions, a natural antibacterial agent

When metallic silver is in water or in the air (there is a certain amount of water in the air), a small amount of silver ions will be released from the surface of silver, so it has a certain antibacterial effect. People have been using silverware since ancient times. It has been found that milk in silver bowls is not easy to spoil, food is not easy to spoil, silver earrings do not cause skin infections and inflammations, and monks in Southeast Asia are still using silver bowls for alms. These are all examples of human empirical use of silver's antibacterial effect. As an antibacterial agent, silver ion has the advantages of safety, broad-spectrum, long-term effect, non-resistant bacteria, and obvious bacteriostatic effect. It is a very ideal antibacterial agent. Silver ion-intolerant bacteria appear, that is, bacteria have no resistance to silver ions, which is caused by the unique sterilization mechanism of silver ions.
