 Abstract

The implant associated infections (IAI) have been identified as one of the primary causes of bone implant failures. A novel silver based antimicrobial surface produced on Ti6Al7Nb substrates by plasma electrolytic oxidation was developed to tackle IAI . The effect of steam, dry and Ultra Violet (photocatalytical) sterilisation on this novel material was investigated. The surface topography and oxide structure was not influenced much by the sterilisation technique. The surface wettability was enhanced on UV sterilised samples. The Scanning electron microscope (SEM) analysis performed along with the Energydispersive X-ray spectroscopy (EDS) revealed Ca-P based needle like structure formation on the steam sterilised surface. The silver release rate analysis indicated enhanced release of silver after dry sterilisation and lessened release of silver after UV sterilisation.
