Silver's monetary value is lower than gold, but the medical value of silver should not be underestimated in the treatment of infection. When antibiotics fail, the colloidal silver shows its effect. The doctor believes that colloidal silver is a natural drug that can resist "hundreds of pathogens". It is proved by the professor that silver nanoparticles can kill yeast and have good anti-fungal ability under various conditions. Prevention of oral infections is effective.
Nano silver particle size of around 25 nm mostly, on escherichia coli, neisseria gonorrhoeae, chlamydia trachomatis and other dozens of pathogenic microorganism has strong inhibition and killing effect, and will not develop resistance. Cotton socks made from nano-silver and combed cotton fibers have good antibacterial and anti-odor effects.
Due to its good conductivity, nano silver particles have a very important position in microelectronics. The surface effect and quantum size effect of silver nanoparticles have some special applications, such as surface enhanced Raman application and medical application.
1. Nano silver is a powder silver single substance with a particle size less than 100nm and generally between 25 and 50 nm.
2. The performance of nano-silver is directly related to its particle size.
The study found that the smaller the particle size, the stronger the bactericidal performance.
Short-term washing does not affect its function; With natural color, color, the application does not affect after dyeing, can completely replace lead, tin welding, long-term use of nano silver antibacterial will be formed in the organisms which will deposit of biological, harmful effect on the human body and deposit too much even have obvious toxicity, nano silver to evaporate into the environment will also have effects on the ecological, will destroy the environment beneficial bacteria in the body, plastic products of nanometer silver precipitation after no longer have the function of sterilization, general in the three months to half a year time, use for a long time will be harmful to the body, cause poisoning symptoms, affect the physical development.
Nanometer (nm) is the smallest unit of measurement that follows micron, and one nanometer is one millionth of a millimetre, or millimicron, or billionths of a metre. Nano silver, is the use of cutting-edge nanotechnology will silver nano, nanotechnology, the silver in the state of sterilization ability has a qualitative leap, few can produce powerful antiseptic effect of silver nanoparticles can kill more than 650 kinds of bacteria in minutes, broad-spectrum sterilization and without any resistance, can promote the healing of the wound, cell growth and repair damaged cells, without any toxic effects, also found no stimulation to the skin reaction, this to the wide application of nano silver antibacterial opened up broad prospects, is the latest generation of natural antibacterial, sterilization silver nanoparticles has the following features:
Nanosize silver particles directly into bacteria combine with oxygen metabolism enzyme (SH), the bacteria suffocated the unique mechanism of action, the exposure can be killed by most bacteria, fungi, mold, spores and other microorganisms. By eight major domestic authority study found: the drug-resistant pathogens such as e. coli resistance, resistance to golden staphylococcus, pseudomonas aeruginosa resistant, fester streptococcus, resistant enterococcus, anaerobic bacteria such as comprehensive antimicrobial activity; Bacteria such as staphylococcus aureus, escherichia coli, pseudomonas aeruginosa, candida albicans, and other G +, g-sex pathogens have bactericidal effect on the common bacteria of scald and wound surface. It also has a powerful bactericidal effect on chlamydia trachomatis and gonococcus of sexually transmitted diseases.
One antibiotic can kill about six pathogens, while nanosilver can kill hundreds of disease-causing organisms. Killing bacteria, fungi, trichomonids, branches/chlamydia, gonococcus, bactericidal action, and anti-bacterial resistant bacteria have the same effect!
According to the study, Ag can kill more than 650 bacteria in a matter of minutes. Silver nanoparticles and pathogenic bacteria cell walls/membrane after combination, can directly enter the bacteria, rapid thiol and oxygen metabolism enzyme (SH), enzyme inactivation, blocking breathing metabolic choked to death. The unique mechanism of sterilization allows nanoparticles to kill pathogenic bacteria rapidly at low concentrations.
Permeability is strong
The permeability of silver nanoparticles with super, can rapidly penetrate into subcutaneous 2 mm sterilization, drug resistance to common bacteria, bacteria, bacteria and fungi causing a deep tissue infection has good antiseptic effect.
