Silver nanoparticle Background An antibacterial substance, silver is an old one. Ancient Egyptians protected wounds from bacterial infections with silver. Mongolian herders knew that silver containers were used to prevent milk spoilage more than 1,000 years ago. There are numerous examples today of silver used to prevent bacteria in our daily lives. For skin injuries, doctors will apply gauze made from silver silk to the wound. The shelf life of foods can be extended by using silver containers. The widespread use of silver nanoparticles as antibacterial substances has been made possible by the advent of nanotechnology. Silver nanoparticles (SNP)have the benefits of high efficiency and wide spectrum. They are currently at the center of research into antibacterial materials. There is still much to be learned about the antimicrobial properties of SNPs. Silver antibacterial substances were not used after antibiotics were discovered in 1930s. The abuse of antibiotics has led to a significant problem with drug resistance. SNP has brought attention to new, low-cost antibacterial products that are safe for everyone.
Safety with Nano Silver PowderSilver Nanoparticle is an antibacterial agent, but it is heavy metal. Researchers have performed relevant experiments in order to address this issue. Toxicological Sciences journal published two studies in 2010 that examined the effect of silver nanoparticles at different levels and sizes on cells. This involved contacting the cells directly with the nanoparticles to observe how they react. A concentration of 10g/mL was determined to cause spermatogonia to stop growing. The particle size of the silver nanoparticles, at 10-25nm, would also interfere. Two keys are required to make this work: one is the technique, the other is the concentration. This is the problem. The first is to get the cells to come into direct contact. It would require 10 g/ml in order to cause damage. In most cases, direct contact with cells would be impossible. The Taiwan Institute of Labor Health and Safety found out that silver nanoparticles can’t enter the human body even in very high amounts (300 g/mL) according to normal contact. Even if the nanoparticles do reach the human body they will remain in the cuticle until they are metabolized by skin. This means that it is extremely challenging to get silver nanoparticles into the human body. The nano-silver powder acts as an effective antibacterial agent.
Benefits of Nano Silver PowderSNP’s antibacterial properties are excellent. SNP security is excellent. SNPS have a stronger antimicrobial effect than silver ions. They are also less toxic for mammals, and cause fewer complications. Persistence is another advantage. The SNP can also be placed on chitosan, other carriers and continuously released zero-valent silverions. It maintains a fairly stable silver concentration and is therefore able to achieve its purpose. Third, broad-spectrum antibacterial. SNP has the ability to kill HIV-1 and more than 700 other pathogenic bacteria. SNP is able to kill bacteria and prevent it from becoming resistant. SNP is also safe, has low toxic side effects, and can be used easily. Tungstenmolybdenummetals (aka. Tungstenmolybdenummetals is an advanced material.
