Nano silver is the simple substance of metallic silver with nanometer size. Most of the silver nanoparticles are around 25 nanometers in size, and they have strong inhibitory and killing effects on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae and Chlamydia trachomatis. And there will be no drug resistance. Cotton socks made of nano silver and combed cotton fibers have good antibacterial and deodorizing effects.The study found that the smaller the particle size of silver, the stronger the sterilization performance.

Nano silver has a good long-lasting bactericidal effect and is widely used in industrial antibacterial.At the same time,nano silver powder has high surface activity and catalytic properties, and is widely used in catalysts.
