Silver poses minimal health risks to humans through occupational or therapeutic exposure, and clinicians widely accept that it is a highly effective antibacterial agent in wound care. Silver is inert in its metallic form, but readily ionises in the presence of body fluids and wound exudate to become reactive. This activated silver ion is absorbed by a wide range of bacteria and fungi and is lethal to many pathogenic strains.
