Some basic knowledge about nano silver colloid
In the pre-antibiotic era when nanotechnology has not yet come out, it is difficult to promote silver antibacterial technology except for grinding silver powder, cutting silver wire, and synthesizing silver-containing compounds. The silver compound must be controlled within a certain concentration range, otherwise it will cause harm to the human body. For example: 0.5% silver nitrate is the standard solution for treating burns and wounds; 10-20% silver nitrate solution can be used to treat cervical erosion. The bactericidal effect of the drug is the silver ion itself, and when the concentration is high, the nitric acid will cause great harm to the human body. Therefore, the concentration must be controlled within the human body’s tolerance range. The silver ions in the nano-silver colloid are free to diffuse in deionized water or purified water, and there is no need for “all things” to participate in the role, and any concentration can be selected to complete the sterilization task according to needs! This is the difference between nano-silver colloid and other silver-containing drugs.
Nano silver colloid refers to a liquid with a solute between 1-100nm and stable performance.
Nano silver colloidal antibacterial liquid is the guardian of our lives. In the contemporary era of the proliferation of antibiotics, the living environment is severely damaged. Medicines are indispensable for health maintenance, and medicines have certain toxic side effects, especially the resistance to antibiotics is even more worrying. In addition to the use of drugs, the antibacterial disinfection in our lives is high temperature treatment, which has considerable limitations and brings many inconveniences to our lives. The emergence of nano-silver colloidal antibacterial agents has rewritten the eternal conclusion that human beings are “three-part poison”. Nano-silver colloidal antibacterial agent is not only non-toxic and tasteless, but harmless to the human body. It only kills the single cells of bacteria and viruses, and has a certain healing effect on human wounds. Since then, the antibacterial disinfection in our lives has become simple, convenient, safe and efficient.
Antibacterial characteristics of nano silver colloid
1. Broad-spectrum antibacterial
Nano-silver particles directly enter the bacteria and combine with oxygen metabolism enzymes (-SH) to suffocate the bacteria and kill most of the bacteria, fungi, molds, spores and other microorganisms that come into contact with them. According to the research of eight domestic authoritative institutions, it has comprehensive antibacterial activity against drug-resistant pathogens such as drug-resistant Escherichia coli, drug-resistant Staphylococcus aureus, drug-resistant Pseudomonas aeruginosa, Streptococcus pyogenes, drug-resistant Enterococcus, anaerobic bacteria, etc.; It has a bactericidal effect on common bacteria on the surface of burns, scalds and wounds such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and other G+ and G-sex pathogenic bacteria; it has bactericidal effect on Chlamydia trachomatis and causes sexually transmitted diseases Neisseria gonorrhoeae also has a powerful bactericidal effect.
2. Strong sterilization
According to research, Ag can kill more than 650 kinds of bacteria in a few minutes. After nano-silver particles are combined with the cell wall/membrane of pathogenic bacteria, they can directly enter the bacteria and quickly combine with the sulfhydryl group (-SH) of oxygen metabolizing enzymes to inactivate the enzymes and block respiratory metabolism, causing them to suffocate and die. The unique bactericidal mechanism enables nano silver particles to quickly kill pathogenic bacteria at low concentrations.
3. Strong permeability
Nano-silver particles have super permeability, can quickly penetrate 2mm under the skin to sterilize, and have a good bactericidal effect on common bacteria, stubborn bacteria, drug-resistant bacteria and deep tissue infections caused by fungi.
4. Promote healing
Improve the microcirculation of the tissue around the wound, effectively activate and promote the growth of tissue cells, accelerate the healing of the wound, and reduce the formation of scars.
5. Long lasting antibacterial
Nano silver particles are produced by patented technology, with a protective film outside, which can be gradually released in the human body, so the antibacterial effect is long-lasting.
6. High security
After experimental investigations, it was found that mice did not have any toxic reaction when the maximum tolerated oral dose was 925 mg/kg, which is equivalent to 4625 times the clinical dose. In rabbit skin irritation experiments, no irritation was found. Its unique The sterilization mechanism will not have an effect on human tissue cells while sterilizing.
7. No resistance
The unique antibacterial mechanism of nano silver particles can quickly and directly kill bacteria and lose their ability to reproduce. Therefore, the next generation of drug-resistant particles cannot be produced.
The production of nano-silver colloids requires advanced technology. Hongwu Nano engineers have mastered the most intelligent design process. The produced nano-silver colloids have stable quality, large capacity and excellent antibacterial effects. Sterilization test for the most difficult to kill Staphylococcus aureus and Escherichia coli, the antibacterial activity reached 99.99%.
