The present invention relates to methods and compositions, for antimicrobial silver compositions comprising silver nanoparticles. The present invention further comprises compositions for preparing silver nanoparticles comprising at least one stabilizing agent, one or more silver compounds, at least one reducing agent and a solvent. In one aspect, the stabilizing agent comprises a surfactant or a polymer. The polymer may comprise polymers such as polyacrylamides, polyurethanes and polyamides. In one aspect, the silver compound comprises a salt comprising, a cation and a silver anion. The anion may comprise saccharinate derivatives, long chain fatty acids, and alkyl dicarboxylates. The methods of the present invention comprise devices with silver nanoparticle compositions, which include but are not limited to, such devices as tissue wound care materials, catheters, patient care devices and collagen matrices. The present invention further comprises treating humans and animals with the antimicrobial devices described herein. |
