5 The present invention comprises 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 10 polymer may comprise polymers such as polyacrylamides, polyurethanes, and polyamides. In one aspect, the silver compound comprises a salt comprising a silver cation and an anion. The anion may comprise saccharinate derivatives, long chain fatty acids, and alkyl dicaboxylates. The methods of the present invention comprise treating devices with the silver nanoparticle compositions, including, but not limited to, such 15 devices as woven wound care materials, catheters, patient care devices, and collagen matrices. The present invention further comprises treatment of humans and animals with the antimicrobial devices described herein. 2482288_1 (GHMatters) P71379 AU o 0.2 350 400 450 500 550 Wavelength (nm) Fig. 1 - 1 .0 , o 0.8 e 0 5 S S0.6 00 E e o 0.2 s z 0 0 p 350 400 450 500 550 Wavelength (nm) Fig. 2 |
