Cytotoxic and Bacteriostatic Activity of Nanostructured Coatings
Journal Title: Polish Journal of Microbiology - Year 2016, Vol 65, Issue 2
Abstract
Nanostructures are structures, mainly synthetic (nanosurfaces, cylindrical nanotubes, and nanospheres), which range between 1–100 nm in at least one dimension and can be engineered to a wide range of physical properties. This paper aims to explore the bacteriostatic and cytotoxic characteristics of nano-TiO[sub]2[/sub] coated specimens of glass, stainless steel and ceramic with different thickness and roughness. The results show that stainless steel and glass specimens with a nano-TiO[sub]2[/sub] coating thickness of 200 nm have a bacteriostatic effect of 97% and 100%, respectively after 30 minutes of UV exposure. Glass specimens with a nano-TiO[sub]2[/sub] coating thickness of 750, 200 and 50 nm have a bacteriostatic effect of 86%, 93% and 100% after 60 minutes. Nano-TiO[sub]2[/sub] coatings show a great bacteriostatic but not a cytotoxic effect, thus representing a valuable alternative for biomedical applications.
