General description

Coating is metallic silver and its salts are popularly used in medicinal purposes and in medical devices. The larger surface area to volume ratio and greater reactivity of nano-silver are prominently used in modern biomedical applications and drug delivery.

Application

Water based ink was formulated with the silver nanowires. Silver nanoparticles, leading to higher amounts of elutable substances has been studied. The immunological adjuvant effect of silver nanoparticles (AgNPs) was investigated both in vitro and in vivo Silver nanoparticles based graphite epoxy nanocomposites have been fabricated. Action of AgNPs in enhanced thrombus formation as a consequence of increased platelet aggregation and procoagulant activity has been investigated. Optical fiber sensor photodeposited with AgNPs have been fabricated. PAN fiber based nanocomposites containing Ag and Hydroxyapatite as nanoadditives have been reported.
