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 (ag nanoparticles), or nano silver, is metal Silver of a nanoscale.

Does Nano Silver have any health benefits?
The nanosilver size is usually around 25 nanometers. It has a strong inhibitory and killing effect against dozens pathogenic microorganisms like Escherichia coli, Neisseria gonorrhoeae or Chlamydia trochomatis and does not create 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 cell surface after anchoring. The accumulation of silver nanoparticles may cause denaturation in cell membranes.

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

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 or balance out the oral biofilm when reducing acids. Nano Silver can be applied at much lower levels and penetrates biofilms very easily.
nanosilveris powdered elemental silver, particle size of which is less than or equal to 100nm. The average particle size ranges 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 is easily dissolved into a wide range of solvents including water, isopropyl, ethanol or acetone to form 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.

It is one of the most trusted global silver powder suppliers. Please feel free to contact us at any time for the latest nano price.

Description of Nano Ag Silver Cas 7440-22-4 :
Micronized silver or Ag nano powder refers to a type of metallic argent with nano-scale particle size.

The nano silver particle size is usually around 25nm. Animals were not poisoned by silver nanoparticles even if they were used in thousands of folds more than standard dose.

In the meantime, it also helps repair epithelial damaged cells. The antibacterial properties of Ag nanoparticles are enhanced in water.
The experts think that this nano-silver antibacterial nanopowder is suitable for a wide range of applications, such as textiles, clothing and fresh fruit.

What is the production process of nano Ag silver particles ?
Nano-silver is prepared in a variety of ways. These include the vacuum condensation method, physical crushing method, mechanical ball milling, and photoreduction method. Chemical methods include the reduction method. Electrochemical reduction method. Photoreduction method. Gas-liquid 2-phase method. Hydrothermal synthesis. Precipitation method. The methods for preparing silver nanoparticles has become increasingly mature. Cost and efficiency of production have also reached a level that is suitable for large-scale 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 Silver Nano powder
The nanosilver particles, are the most attractive of all nanomaterials. These particles have been widely applied in many biomedical fields, such as drug delivery, diagnosis, treatment, 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, in water treatment or in consumer goods (clothing, cosmetics, child care items, food containers and more).
1. The nano-silver powder may be used in pharmaceuticals as an antibacterial or disinfectant.
2. Some countries use ag nanoparticles in anti-AIDS drugs mixed with zinc dioxide powder for disinfection.
3. The powder of silver metal can be used as a catalyst.
4. The Nano silver powder as Antivirus Antibacterial Material: By adding 0.1% of silver nanoparticles in the form of inorganic antibacterial particles, it can help to suppress and kill dozens of pathogenic bacteria such as Escherichia colitis, Staphylococcus aureus.
5. Nano-Silver Ag Nanoparticles as a new product with anti-infective properties that are non-resistance and free of pH effects. They also have antibacterial and durable properties.
6. In addition to the preservation and construction of relics, nano silver powder can 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 for current applications: Toys. Baby pacifiers. Clothing. Food storage containers. Face masks. HEPA filters. Laundry detergent. Conductive slurry
8. Silver nanoparticles have a major role to play in the reduction of electronic circuits and 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 mutation 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 ?
Silver Ag powder is available in a variety of different packaging options.
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 air or sea as soon after payment receipt.
