Silver containing hybrid coatings were synthesized on titanium by sol-gel process. The specimens were studied by transmission electron microscopy, field-emission scanning electron microscopy, bonding test and bacterial counting method. The solid phase content of the sols was increased by the addition of TiO 2 nanoparticles, which avoided the formation of microcracks on the coatings surface. The bonding strength of the coated groups showed a bonding strength improvement of 10.6% compared to the uncoated group. The percent reduction in bacterial count against S. aureus seeded on silver containing hybrid coating surface was approximately 99.3% after 24h incubation, which indicated the strong antibacterial activity of the coating.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
