Nano Silver is Silver in a form of nanoscale particles. Nano silver has a killing and inhibiting effect on many pathogenic microorganisms. Purity>99%
Particle size range: 20 to 500nm

About The Nano Silver Ag Powder
Silver is Ag. Silver Nanoparticles (also called Nano Silver or Ag nanoparticles), is a metal Silver of a nanoscale.

Is Nano silver healthy?
The nanosilver size is usually around 25 nanometers. This has a strong inhibitory and killing effect against dozens pathogenic microorganisms like Escherichia coli, Neisseria gonorrhoeae or Chlamydia trochomatis and won't produce drug resistance. Cotton socks are made of nanometer-sized silver and combed fiber cotton. They have antibacterial, deodorant and antifungal properties.

Does Nano Silver kill germs
Silver nanoparticles, apart from being able release silver ions themselves, can kill bacteria. Silver nanoparticles are able to accumulate on the surface of the cell after anchoring. Silver nanoparticles that accumulate on cell membranes can denaturize them.

Does Nano Silver kill the good bacteria?
Silver Nanoparticles have a significant role in microelectronics due to their excellent conductivity. Due to their surface effect and quantum-size effect, silver nanoparticles are also used in some special applications such as surface enhanced Raman applications or medical applications.

Is colloidal or nano-silver better?
Coloidal silvercannot use with other beneficial agents, and has only a weak impact on biofilm. This means that it is not able to protect the enamel and balance the oral microbiofilm by reducing acids. Nano Silver can penetrate biofilms at low concentrations.
nanosilver is a powdered elemental of silver, particle size between 25-50nm. The size of the silver nanoparticles is directly related to its properties. According to studies, the smaller the particle sizes are, the better the bactericidal properties.

What are the side effect of nano-silver?
Silver nanoparticles are absorbed by the lungs, intestines and skin and can reach the liver, kidneys, spleens, brains, hearts and testes. Nanosilver is known to cause mild irritations of the skin and eyes. It may also cause mild skin allergies.
Silver Nanopower/Nanopower can be used for pharmacological purposes, antimicrobial uses, conductive applications and chemical applications. Nanopower can easily be dispersed in various solvents such as water, alcohol and isopropyl, to make a convenient solution. Researchers continue to discover new uses for silver nanoparticles, such as in biotechnology and medicine. They also find them useful in electronics, manufacturing, and electronic devices.

Description of Nano Ag Silver Cas 7440-22-4 :
Micronized silver, or Ag Powder, is a type of metallic argent with nanoscale particle size.

The nano silver particle size is usually around 25nm. Animals were not poisoned by silver nanoparticles even when the dosage was thousands of time higher than the standard dose.

It helps repair the epithelial damaged cells. The antibacterial properties of Ag nanoparticles are enhanced in water.
Experts think that this nano-silver antibacterial nanopowder could be used for a wide range of applications, such as in textiles and clothes, fresh food, health, and the protection of the environment.

What is the production process of Nano Ag silver powder ?
Nano-silver is prepared in various ways. These include the vacuum condensation method, physical crushing method and mechanical milling method. Chemical methods include the reduction method. Electrochemical reduction method. Photoreduction method. Gas-liquid 2-phase method. Hydrothermal synthesis. Precipitation method. Silver nanoparticles preparation methods are becoming more and more refined, with cost and efficiency reaching the level of industrial production. Nano-silver particle's development prospects are very wide, as they are a brand new material. This is true for fields such as medicine, biology and the environment.

Uses of Nano-silver powder
The nanosilver particles, are the most attractive of all nanomaterials. These particles have been used for a wide range of biomedical purposes, such as drug delivery, diagnosis, medical device coatings, and personal care.

What is the purpose of nano silver?
Nanosilver contains silver nanoparticles. These particles can be used in industrial products, water treatment, consumer goods (clothing, cosmetics, children's items, food containers and more) and as antibacterial and antibiotic agents.
1. The nano-silver powder may be used in pharmaceutical antibacterial or disinfectant applications;
2. Some countries use Ag Microparticles in anti-AIDS drugs mixed with zinc dioxide powder for disinfection.
3. The metal powder can be used as a chemist's catalyst.
4. Also, the nano silver powder is used as Antivirus Antibacterial material. Adding 0.1% of silver nanoparticles can be an important part of the suppression and death of dozens micro-organisms including Escherichia colitis, Staphylococcus aureus.
5. Nanoparticles of silver Ag nanoparticles, a new product with anti-infective properties that are non-resistance and pH-free, can be used to make medical and household fabrics, and in health care products. They also have antibacterial and durable properties.
6. In addition to the preservation and construction of relics, nano silver powder can also be added as an antibacterial coating.
These manufacturers produce products that use the antibacterial properties provided by silver nanoparticles. The nano-silver coatings are used on refrigerators with air conditioners or washing machines.
7. The nano silver powder can be used in other applications such as: toys, clothing, food containers, masks for the face, HEPA filters and laundry detergent. Conductive slurry
8. The silver nanoparticles in nano silver powder are widely used to wire, encapsulate and connect in microelectronics. This helps in minimization of electronic devices. Silver nanoparticles have a high efficiency and speed of chemical reaction, for example, ethylene oxidation. Biological pharmacy
9. The nano-silver powder can be used to diagnose gene mutations and cell death.

Storage Conditions of Nano Ag Silver Powder:
Ag powder performance and effects will be affected by dampness. Therefore, Ag silver powder should be packed in vacuum and stored in cool, dry rooms. The silver Ag can't be exposed to the air. Ag powder is also not to be used under pressure.

Packing & Shipping Nano Ag silver powder ?
There are different packing options depending on the amount of silver Ag.
Silver Ag powder packaging: Vacuum packed, 100g/bag, 500g/bag or 1kg/bag. 25kg/barrel or your request.
Silver Ag Powder Shipping: Could be shipped by sea, air, or by express as soon after payment receipt.
