About The Nano Silver Ag Powder

Silver is Ag. Silver Nanoparticles (or ag-nanoparticles), or nano-sized silver, is metal Silver.

Is Nano silver healthy?

The nanosilver size is usually around 25 nanometers. This has a strong inhibitory and killing effect against dozens of pathogenic bacteria such as Escherichia Coli, Neisseria Gonorrhoeae, and Chlamydia Trachomatis. And it will not cause 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

In addition to their ability to release silverions, nanoparticles of silver 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 and balance the oral microbiofilm by reducing acids. Nano Silver can be applied at much lower levels and penetrates biofilms very easily.

nanosilver is a powdered elemental of silver, with particle sizes less than or equal to 100nm. They are usually 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, intestine and skin and can reach the liver, kidney, testes and brain. 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, producing 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 nano powder refers to a type of metallic argent with nanoscale particles.

Most nano silver particles have a size of around 25nm. Animals were not poisoned by silver nanoparticles even if they were used in thousands of folds more than standard dose.

It helps repair damaged epithelial cellular. The antibacterial properties of Ag nanoparticles are enhanced in water.

The experts think that this nano-silver antibacterial nanopowder could be used for a wide range of applications, such as in textiles and clothing and fresh food, health and the environment.

What is the production process of Nano Ag silver powder ?

Nano-silver is prepared in several ways: by crushing it, by vacuum condensation or by mechanical ball milling. 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 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 agents.

1. The nano-silver powder may be used in pharmaceuticals as an antibacterial or disinfectant.

2. Several countries use Ag Microparticles in anti-AIDS drugs mixed with zinc oxide for disinfection.

3. The metal powder can be used as a chemist’s catalyst.

4. The nano-silver powder is also used as an antibacterial antivirus material. By adding 0.1 % silver nanoparticles (the inorganic antibacterial dust), it can be effective in suppressing and killing pathogenic microorganisms like 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 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 minimising electronic devices and circuits. 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.
