Properties

It is known as silver nanoparticles suspension with the size distribution of 10-40 nm. Some crystalline phases such as Ag, AgCl and NaNO3 have been observed in its XRD pattern. Concentration of silver ions is 2000 ppm in it. It also shows antibacterial activity compatible with INSO 2842 after dilution in accordance with the instruction. In nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species. It is reported that these nanoparticles have significant antifungal activities against some ringworms. Ag nanoparticles interact with sulfur and phosphorus compounds of membrane proteins affecting cell morphology and structure, causing its death. With decreasing particle size, the release of silver ions increases, leading to increasing their antibacterial activities.

Manufacturer's Description

Nanosilver in the form of colloidal silver has been used for more than 100 years. So-called colloidal silver, which contains silver of different concentrations and particle sizes, has historically mainly been used for treatment of wounds and infections. Introduction of silver into bacterial cells induces a high degree of structural and morphological changes, which can lead to cell death. Silver nanoparticles can prevent bacteria from growing on or adhering to the surface. This can be especially useful in surgical settings where all surfaces in contact with the patient must be sterile. Interestingly, silver nanoparticles can be incorporated on many types of surfaces including metals, plastic, and glass. In medical equipment, it has been shown that silver nano particles lower the bacterial count on devices used compared to old techniques.
