<p>Disclosed is a composition comprising, a solvent, silver nanoparticles, wherein the silver nanoparticles are made by admixing in no particular order, an aqueous solution of a stabilizing agent, an anionic donating solution, and a soluble silver salt solution, and (b) adding an amine other than a tertiary diamine, wherein the amine triggers the formation of elemental silver nanoparticles. The disclosure further relates to a method of treating a surface with elemental silver nanoparticles, comprising, (a) contacting a surface with a solution comprising silver nanoparticles for a time sufficient for an effective amount of nanoparticles to bind to the surface, and (b) rinsing the solution from the surface, wherein the elemental silver nanoparticles are made by admixing in no particular order, an aqueous solution of a stabilizing agent solution, an anionic donating solution and a soluble silver salt solution, and adding an amine solution other than a tertiary diamine solution.</p> |
