Overview of Silver Nanoparticles (Nano Ag Powder)

Nano Silver is a metal Silver with a particle size of nanoscale. Is Nano Silver healthy? 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. Made of nanometer silver and combed cotton fiber, cotton socks have good antibacterial and deodorant effects. 

Characteristics of Silver Nanoparticles

Silver/Ag nanoparticle is a kind of metallic silver with nano scale particle size.

Most of the nano silver has a particle size around 25 nm. According to the tests on Animals, there is no exhibition of being poisoned even if the dosage of silver nanoparticles is thousands of times used more than the standard dose.

Meanwhile, it helps to repair the damaged epithelial cells. What worth to be mentioned is that the antibacterial effects of Ag nanoparticles become more enhanced when in water, which is more effective to the treatment of diseases.

The experts believe that this nano silver anti-bacterial nanopowder can be widely used in the field of environmental protection, textiles and clothing, fresh fruit, food and health.

Application of Silver Nanoparticles  

Nanosilver particles (NSPs), are among the most attractive nanomaterials and have been widely used in a range of biomedical applications, including diagnosis, treatment, drug delivery, medical device coating, and personal health care. What is nano silver used for? Nanosilver is made up of silver nanoparticles. These particles serve as antibacterial and antifungal agents for industrial purposes, in water treatment, and in consumer products (such as clothing, cosmetics, childcare items, food containers, and many others).

1. The nano silver powder can be used as a pharmaceutical antibacterial, disinfectant;

2. Some of countries use Ag Nanoparticles for anti-AIDS drugs, mixed with zinc oxide powder for disinfection;

3. The nano silver powder used as a chemical catalyst.

4. Also, The nano silver powder used as Antivirus antibacterial material: adding 0.1% silver nanoparticles, the inorganic antibacterial powder, can play an important role in the suppression and killing of dozens of pathogenic micro-organisms such as Escherichia coli, Staphylococcus aureus.

5. Silver nanoparticles as a new anti-infective product which has broad-spectrum, non-resistance, free from the pH effects, antibacterial, durable, non-oxidized black and many other properties, Ag Nanoparticles can be widely used in medical, household fabrics and health care supplies.

6. Adding nano silver powder as antibacterial, anti-corrosion coating paint materials can also be used successfully in the construction and preservation of relics.

Manufacturers produce household items that utilize the antibacterial properties of silver nanoparticles. These products include nano-silver lined refrigerators, air conditioners and washing machines.

7. The nano silver powder for Other current applications: Toys, Baby pacifiers, Clothing, Food storage containers, Face masks, HEPA filters, Laundry detergent. Conductive slurry:

8. The nano silver powder is Widely used for wiring, encapsulation and connection in the microelectronic industry, silver nanoparticles play an important role in the minimization of electronic devices and circuits. Efficacious catalyst: silver nanoparticles can Greatly enhance the chemical reaction speed and efficiency, such as Ethylene oxidation. Biological pharmacy:

9. The nano silver powder can be used in cell death and gene diagnosis.

FAQ

Q1:

Is Nano Silver healthy? 

Re: 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. Made of nanometer silver and combed cotton fiber, cotton socks have good antibacterial and deodorant effects.

Q2:

Does Nano Silver kill germs? 

Re: In addition to being able to release silver ions, silver nanoparticles can themselves kill bacteria. Silver nanoparticles can accumulate in the pits that form on the cell wall after they anchor to the cell surface. The accumulated silver nanoparticles can cause cell membrane denaturation.

Q3:

Which is better nano silver or colloidal silver? 

Re: 

Colloidal silver cannot be used with other beneficial agents and has a weak effect on the biofilm. Therefore, it does not do a sufficient job protecting enamel and balancing the oral biofilm by reducing acid. Nano Silver can be used at much lower concentrations and can penetrate biofilms with ease.

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. Studies have found that the smaller the particle size, the stronger the bactericidal performance. 

Q4:

What are the side effects of nano silver?

Re: Silver nanoparticles may be absorbed through the lungs, intestine, and through the skin into circulation and thus may reach such organs as the liver, kidney, spleen, brain, heart and testes. Nanosilver may cause mild eyes and skin irritations. It can also act as a mild skin allergen.
