Merck, 576832-5G, Silver

This silver nanopowder consists of metallic silver nanoparticles with a diameter less than 100 nm. These nanosilver particles are coated with polyvinylpyrrolidone (PVP) at a concentration of 0.2% by mass. This coating effectively limits surface oxidation and enhances the dispersion of the powder in various solvents. Silver nanopowder is extensively utilized in medicinal applications and medical devices. The increased surface area to volume ratio and heightened reactivity of nanosilver make it particularly valuable in modern biomedical applications, particularly in coatings of medical devices.
