The effect of selenium nanoparticles on antibacterial and cellular properties of titania nanotubes

Popis výsledku v původním jazyce

To date, most of the materials used in tissue engineering such as titanium and its alloys suffer from the susceptibility to bacterial infections. The potential use of antimicrobial nanoparticles can make the material less susceptible to formation of biofilm, which could lead to increased success rate of individual applications. In our work we prepared TiO2 nanotubes via anodic oxidation in organic electrolyte containing ethylene glycol, ammonium fluoride and water. As a substrate we used thin titanium film with thickness of 500nm deposited onto 4-inch p-type silicon wafer covered by 500nm of thermal silicon dioxide. Anodic oxidation resulted in nanotubular surface with nanotube diameter of approximately 50 nanometers. To convert fabricated TiO2 nanotubes from amorphous to crystalline state, they were annealed at 450 °C for 3 hours. The annealed samples were further decorated with various concentrations of chemically synthesized selenium nanoparticles. Selenium nanoparticles were prepared by the reacti
