4 Layers Disposable KN95 Face Mask With Antibacterial And Antiviral Fibres

Antiviral mechanism of silver:

Silver is a typical metal material, It has a large specific surface area and the particle

size is very small. The percentage of surface atoms increased make amount of surface

atoms increased, there are no adjacent atoms around to lead many unsaturated

bonds, which have unstable atoms with high surface energy. This structure provides

many contact adsorption sites and reaction points in various reactions. It is easy to

bond with foreign atoms by chemical bonds, which increases ability of absorbing

viruses and strengthens chemical reaction capacity among viruses mutually.

the following information:

1. Silver has mechanical adsorption and fixation of the virus. The surface of the

metal ultramicro particles is covered by a layer of polymer which is 5 to 10

meters thick. It can immobilize a large number of proteins and enzymes,

especially polysaccharides. Many polysaccharides may block the adsorption of

viruses to host cells, showing strong antiviral activity. Meanwhile, due to the

colloidal stability and strong adsorption of metal particles, the virus lost its

survival conditions and died.

2. Silver prevents the virus from entering the host cell, and inhibits its binding to the

cell receptor, and thus prevents the virus from infecting the host cell. Some small

metal molecules can bind to the conserved spatial structure of the surface

protein of the virus to inhibit the interaction between the virus and the receptor.

It can prevent the virus from entering the cell and directly inactivate the virus,

which may be similar to killing bacteria. For example, the silver particle combines

with -- SH of the surface protein of the virion to form -- SAg complex, which

inactivates the enzyme protein, interferes with the entry of the virus into the cell

or kills the virus, leading to the inactivation of the virus.
