The toxicity of antimicrobial silver in products can be reduced
Date:2/24/2010

an even be assumed that silver nanoparticles are cyto- or genotoxic. Moreover, it has been demonstrated that silver nanoparticles penetrate the skin via pores and glands. If the skin is damaged, this facilitates the penetration of silver particles through the skin.

It is therefore important that coatings containing silver nanoparticles do not release nanoparticles. According to Finnish researchers, the effect of the coating should only be based on silver ions dissolving from them. Consequently, nanoparticles should be as well bound to the coating as possible, enabling a reduction in the possible exposure to silver nanoparticles.
