Nano silver powder, ultrafine silver powder, spherical silver powder, flake silver powder, high purity silver powder

Nano silver is a kind of metallic silver with nanometer size. Most of the nano silver particles are about 25 nm in diameter, which can strongly inhibit and kill dozens of pathogenic microorganisms, such as Escherichia coli, Neisseria gonorrhoeae and Chlamydia trachomatis, and will not produce drug resistance. Animal experiments showed that even if the dosage of the nano silver antibacterial powder reached several thousand times of the standard dose, the tested animals had no poisoning performance. At the same time, it can promote the repair of damaged epithelial cells. It is worth mentioning that the antibacterial effect of the product in contact with water is increasingly enhanced, which is more conducive to the treatment of diseases.

Nano silver is the use of cutting-edge nanotechnology to nano silver. The emergence of nanotechnology has made a qualitative leap in the bactericidal ability of silver in the nano state. Very few nano silver can produce strong bactericidal effect, which can kill more than 650 kinds of bacteria in a few minutes. It has broad-spectrum sterilization and no drug resistance. It can promote wound healing, cell growth and repair of damaged cells It is the latest generation of natural antibacterial agent.

Nano silver has the following characteristics: 1

1. Broad spectrum antibacterial

Silver nanoparticles directly enter the bacteria and combine with oxygen metabolism enzyme (- SH), which can kill most bacteria, fungi, molds, spores and other microorganisms. According to the research of eight authoritative institutions in China, it has comprehensive antibacterial activity against drug-resistant pathogens such as drug-resistant Escherichia coli, resistant Staphylococcus aureus, resistant Pseudomonas aeruginosa, Streptococcus pyogenes, resistant Enterococcus, anaerobic bacteria, and other common bacteria such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and other G +, g-sex pathogenic bacteria It also has strong bactericidal effect on Chlamydia trachomatis and Neisseria gonorrhoeae causing sexually transmitted diseases.

One antibiotic can kill about six pathogens, while silver nanoparticles can kill hundreds of pathogenic microorganisms. It can kill bacteria, fungi, trichomonas, Mycoplasma / chlamydia and Neisseria gonorrhoeae. It has strong bactericidal effect, and has the same killing effect on antibiotic resistant bacteria!

2. Strong sterilization

According to the research, a G can kill more than 650 kinds of bacteria in a few minutes. After binding with the cell wall / membrane of pathogenic bacteria, silver nanoparticles can directly enter the bacteria and rapidly combine with thiol (- SH) of oxygen metabolism enzyme, which inactivates the enzyme, blocks respiratory metabolism and causes it to suffocate. The unique bactericidal mechanism makes silver nanoparticles rapidly kill pathogenic bacteria in low concentration.

3. Strong permeability

Silver nanoparticles have strong permeability, can quickly penetrate into the subcutaneous 2mm for sterilization, and have good bactericidal effect on common bacteria, refractory bacteria, drug-resistant bacteria and deep tissue infections caused by fungi.

4. Repair and regeneration

Nano silver can promote wound healing, promote the repair and regeneration of damaged cells, remove putrefaction, promote muscle regeneration, antibacterial and anti-inflammatory, improve the microcirculation of surrounding tissues, effectively activate and promote the growth of tissue cells, accelerate the wound healing and reduce the formation of scar.

5. Long lasting antibacterial activity

Silver nanoparticles are produced by patented technology, with a protective film on the outside, which can be released gradually in human body, so it has antibacterial effect

6. Safety and non toxicity:

As early as "compendium of Materia Medica" records: raw silver, non-toxic; the United States Public Health Bureau in 1990 "on the silver toxicity investigation report" that: silver has no obvious toxic and side effects on human body; nano silver is a local drug, less silver content, is the safest way of medication. It was found that there was no toxic reaction in mice when the maximum oral tolerance dose was 925mg / kg, which was equivalent to 4625 times of the clinical dosage. No irritation reaction was found in the skin irritation test of rabbits.

7. No drug resistance

Nano silver belongs to non antibiotic fungicides: nano silver can kill all kinds of pathogenic microorganisms, which is stronger than antibiotics. The unique antibacterial mechanism of nano silver particles with the size of 10nm can quickly and directly kill bacteria and make them lose their reproductive capacity. Therefore, it is impossible to produce the next generation of drug resistance, which can effectively avoid repeated attacks caused by drug resistance.
