Abstract

Description

Antibacterial product
FIELD
The present application relates generally to the field of sterilization, antibacterial.
Background
Chemical silver and nano silver have rapidly become the most commonly used materials in consumer products, but the most rapidly growing materials in the commercialization field of nano materials. Nano silver is currently used as an antibacterial agent in various products on the market.
Studies have shown that the widespread use of nanosilver can pose serious health and environmental hazards to humans, and can lead to the formation of antimicrobial antibodies, which are reduced in potency. A recent study reviews the evidence of toxicity of nanoparticles currently being studied globally and indicates that there is sufficient evidence that silver nanoparticles may be harmful to the environment and therefore should be used on a prophylactic basis. In particular, nano silver used in electronic and electric devices is finally present in the environment in the form of ions, which are environmentally damaging and also extremely toxic to aquatic organisms at very low concentrations. Silver released from the internal coating of refrigerators and washing machines is particularly dangerous because of the possibility of entering the water body, silver ions are released into the wastewater and finally enter the municipal sewage treatment plant, thereby limiting the growth of beneficial microorganisms of the sewage treatment plant. The presence of such hazardous substances is therefore contradictory to the requirements for establishing a good water ecology.
