PLASMA SPRAYED HYDROXYAPATITE COATINGS MODIFIED WITH SILVER NANOPARTICLES

Abstract

Metallic silver, silver nanoparticles (AgNp) and nanocomposites based on silver are widely used
in medicine, due to their antibacterial and antiseptic properties. The main goals of the present
work were: (1) research of various types of liquids containing AgNp (including AgNp produced
by 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) implant
coatings deposited by plasma spraying; (2) preliminary evaluation of antibacterial properties of
HA coating modified with AgNp. The first test shows significant antibacterial activity of HA
coatings containing AgNp produced by biosynthesis technology.
