The tale of antibacterial behavior of silver is not contemporary, and it was found out and applied, for example during wars, for recovery of soldiers' wounds, put a silver coin on it, and then tied it up, or for keeping the food safe they used silver dishes, they thought contagious diseases didn't incident in rich areas, because of using silver dishes.

Scientists find out different mechanisms for expressing how silver affects on germs. Just because of these mechanisms, germs can not adopt with silver or being resistant.

Today, it is possible for us to produce Nano Silver particles by means of Nano technology.

Nano Silver particles give us this possibility that with the least viscosity in ppm, have the most effective antibacterial behavior.

Between various mechanisms was found of Nano Silver.2 of them were considered obviously, as following

Ion mechanism:

In this mechanism, metal Nano Silver particles gradually, radiate Ag⁺ ions. These ions during replacement reaction change HS^- bands in micro organism's membrane into AgS^- bands, the result of this reaction, are daturation and wasting the microorganism.

Catalectic mechanism:

In this mechanism that is truer about Nano Silver composites.

Semi conductors, Nano Silver particles were put on Semi conductor bases, such as Tio₂ or Sio₂.

In this case, Semi conductor bases, without need to light power, because of decreasing electrons speed between capacity layer and conducting layer, atom get to stability state because of presence of positive cavities and compression of electrons.

In this case particle acts like an electro chemical pile and with oxidant O₂ atom, O₂^- ion with hydrolyze H₂O, produce OH⁺ that both are from active bases (in active O group)that are from the strongest antigerms agent various researches were done on kinds of germs regarding to Nano Silver particles impressing .

Up to now more than 600 kinds of germs were known such as HIV virus , that were been taking impression.

Following is more than 100 kinds of known germs with their reference:
