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.
