Nano silver powder is a new type of antibacterial product developed based on nanotechnology. Due to the quantum effect, small size effect and large specific surface area, it has an antibacterial effect that traditional inorganic antibacterial agents can’t match. It has high safety and long-lasting effectiveness. , Is an antibacterial agent with long-lasting and weather resistance.
Regarding the principle of the bactericidal effect of nano-silver, most scholars believe that the specific surface area of ultra-fine silver is very large and presents AG+ in water. Therefore, the bactericidal effect of nano-silver is mainly related to silver ions, which can be related to the -SH in the enzyme protein in the bacteria. It binds quickly to inactivate key metabolic enzymes, making pathogenic bacteria unable to metabolize and die; secondly, nano-silver can bind to DNA bases of pathogenic bacteria and form cross-links to replace hydrogen bonds between adjacent nitrogens in purines and pyrimidines. Which denatures DNA without being able to replicate, leading to inactivation of pathogenic bacteria. The atomic arrangement of nano-silver shows that it is a “medium state” between solid and molecule. This extremely active nano-silver particle has super antibacterial ability and can kill bacteria, fungi, mycoplasma, chlamydia and other pathogenic microorganisms. In addition, nano-silver is a non-antibiotic bactericide, and no bacteria are resistant to nano-silver.
1. Application in burns, scalds, burn skin grafts
The results of skin grafting for dozens of burn patients showed that nano-silver increased the epithelialization rate of reticuloepithelial grafts by 40%, and had a better effect on promoting repair of residual burn wounds. The healing time of the experimental group was significantly shorter than that of the control group. Researchers believe through clinical observations and animal experiments that nano-silver antibacterial medical dressings are a kind of clinical external medicine for burns with strong anti-infective effect, low absorption, small toxic and side effects, and convenient use.
2. Application in dermatology
Nano silver is effective in treating acne vulgaris. The nano-ulcer patch is used to treat I-II bedsores. In comparison with the control, it is found that the active ingredient of the nano-ulcer patch is nano-silver particles, which has super permeability, produces a biothermal effect, improves the microcirculation of the damaged tissue, and eliminates the local area. Edema is conducive to tissue regeneration and wound healing.
3. Application in dentistry
Nano silver antibacterial agent can be used to prevent oral caries and mucosal diseases, and can also solve the problem of easy pollution during the production and use of dental materials.
In summary, due to its quantum effect, small size effect and large specific surface area, nano-silver materials are easily in close contact with pathogenic microorganisms, thereby exerting greater biological effects, so they have high safety, wide antibacterial range, and continuous Advantages such as long sterilization time. However, nano-silver materials are prone to particle aggregation and lose their nano-characteristics under conventional conditions without protective agents, which will affect the antibacterial effect of nano-materials. Therefore, the packaging and storage of nano-silver are also extremely important. For details, please consult Hongwu Nano staff online our website:https://www.hwnanomaterial.com/.
