Silver Nanoparticles Properties

What is Silver Nanoparticles Nano Ag Powder?

Nano Silver is a metal Silver with a particle size of nanoscale. Nanosilver is a powdered silver elemental, particle size is less than 100nm, generally between 25-50nm. The properties of silver nanoparticles are directly related to their particle size. It was found that the smaller the particle size of silver nanoparticles, the stronger the bactericidal performance.

The size of the nanosilver is mostly about 25 nanometers, which has strong inhibition and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis, and will not produce drug resistance. Silver nanoparticles play an important role in the field of microelectronics because of their excellent electrical conductivity. Due to the surface effect and quantum size effect, silver nanoparticles also have some special applications, such as surface-enhanced Raman applications and medical applications. Is Nano Silver dangerous? Silver nanoparticles may be absorbed through the lungs, intestine, and skin into circulation and thus may reach such organs as the liver, kidney, spleen, brain, heart, and testes. Nanosilver may cause mild eye and skin irritations. It can also act as a mild skin allergen.

Nanosilver particles directly enter the bacteria and combine with the oxygen metabolism enzyme (-SH) to suffocate the bacteria and kill most of the bacteria, fungi, molds, spores, and other microorganisms in contact with them. It has been found by eight authoritative institutions in China that it has a comprehensive antibacterial activity against drug-resistant pathogenic bacteria such as drug-resistant Escherichia coli, drug-resistant Staphylococcus aureus, drug-resistant Pseudomonas aeruginosa, streptococcus pyogenes, drug-resistant Enterococcus and anaerobic bacteria. It has a bactericidal effect on the surface of burns and wounds, such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and other G+ and G- pathogenic bacteria. It also has a strong bactericidal effect on chlamydia trachomatis and gonorrhea, which cause sexually transmitted diseases. TRUNNANO is a trusted global Silver Nanoparticles Nano Ag Powder supplier.

How is Silver Nanoparticles Nano Ag Powder Produced?

There are many methods for the preparation of nanosilver particles, so in recent years, people have been constantly exploring new methods for preparing nanosilver particles, including physical crushing, vacuum condensation, and mechanical ball milling. The chemical method has a reducing method, an electrochemical reduction method, a photo dent reduction method, a gas-liquid two-phase method, a hydrothermal method, a precipitation method, and the like. Because the preparation method of nanosilver particles will be very important for future practical use. The preparation method of nanosilver is gradually maturing, and cost and production efficiency have reached the level of large-scale industrial production.

 Storage Condition of Silver Nanoparticles Nano Ag Powder:

The damp reunion will affect silver nanoparticles' dispersion performance and use effects. Therefore, nano silver powder should be sealed in vacuum packing and stored in a cool and dry room; the nickel nanoparticles can not be exposed to air. In addition, the Ag Nanoparticles should be avoided under stress.


Packing & Shipping of Silver Nanoparticles Nano Ag Powder:

We have many different kinds of packing, which depend on the silver nanoparticles quantity.

Silver nanoparticles packing: vacuum packing, 1kg/bag, 25kg/barrel, or as you request.

Silver nanoparticles shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
