PLASMA SPRAYED HYDROXYAPATITE COATINGS MODIFIED WITH SILVER NANOPARTICLES

Metallic silver, silver nanoparticles (AgNp) and nanocomposites based on silver are widely usedin medicine, due to their antibacterial and antiseptic properties. The main goals of the presentwork were: (1) research of various types of liquids containing AgNp (including AgNp producedby biosynthesis technology using dessert plants (nopal, agave) extracts to reduce the silver); (2)research of sedimentation from liquids of AgNp on the surface of Hydroxyapatite (HA) implantcoatings deposited by plasma spraying; (2) preliminary evaluation of antibacterial properties ofHA coating modified with AgNp. The first test shows significant antibacterial activity of HAcoatings containing AgNp produced by biosynthesis technology.
