As the latest generation of natural antibacterial agents, nanosilver particles have the following characteristics: broad-spectrum antibacterial sterilization without any drug resistance; powerful sterilization, which can kill a variety of harmful bacteria to the human body within minutes Bacteria; strong permeability, can quickly penetrate into the subcutaneous pores for sterilization, and has a good sterilization effect on common bacteria, stubborn bacteria, drug-resistant bacteria and infections caused by fungi; promote healing: improve the microstructure of the tissue around the wound, effectively activate and promote The growth of tissue cells accelerates wound healing and reduces the formation of scars; the antibacterial effect is long-lasting. Nano-silver particles are produced using patented technology and have a protective film on the outside that can be gradually released in the human body, so the antibacterial effect is long-lasting.
The safety of silver nanoparticles is recognized by the international medical community, because trace amounts of silver are originally one of the important elements necessary for the human body. Silver nanoparticles are not charged and do not interact with various biological activities in the human body. The substances are combined and deposited, adsorbing and killing bacteria in the pores, and will be completely discharged from the body without any toxic side effects. In the United States, the safety of nanosilver is considered to be at the same level. Extensive animal experiments have been conducted on the safety of silver. The experimental investigation found that mice did not have any toxic reactions when the oral maximum tolerated dose was 925mg/kg, which is equivalent to 4625 times the clinical dose. In the skin irritation experiment of rabbits, no irritation reaction was found.
Nano silver products are widely used in environmental purification, medical treatment, medicine, cosmetics and other fields. Especially in the fields of medicine, textiles, and cosmetics, silver nanoparticles have huge potential for exploration.
In medicine, today people often use silver nitrate solution containing silver ions as an anti-inflammatory and astringent medicine for the eyes. In some hospitals, a kind of silver gauze and silver cotton wool are also widely used. These gauze and cotton wool are coated with a layer of silver or sprinkled with very fine colloidal silver powder. They are applied to the wound and have good sterilization effect. effect.
In the field of textiles, because some antibacterial agents in clothes have been found to be harmful to the human body, experts believe that the application of nanosilver technology in clothing can provide good breathability and perspiration performance, as well as sterilization and deodorization. It is a new type of green and environmentally friendly antibacterial product.
In the field of cosmetics, in 2002 in South Korea, nano-silver particles were also successfully grafted into the cosmetics industry, filling the gap in the industry of nano-silver particle cosmetics. Nano-silver particle cosmetics, which have both the functions and functions of cosmetics, have been favored by many consumers since their advent.
With the maturity of nano-silver particle technology, its excellent quality and preferential prices have also created increasingly favorable conditions for the popularization and industrial production of more nano-silver antibacterial products.
