Abstract
In present invention, colloidal nanosilver has been prepared with high affect on bacteria, viruses, and fungi. The average size of nano particles are less than 10 nm. In the present invention colloidal nanosilver is subject to synthesis by a very simple method and in a short time. Nanosilver colloid prepared by use of different surfactant like LABS, Tween 20, Tween 60, Tween 80, SDS.
