Antibacterial efficiency of silver-doped layers of titanium alloy Ti6Al4V and 316L steel

Popis výsledku v původním jazyce

Biological, physical and mechanical properties of silver-doped layers of titanium alloy Ti6Al4V and 316L steel prepared by pulsed laser deposition were studied. Thin films of silver and silver-doped materials were synthesized using KrF excimer laser deposition. Material was ablated from one target composed from silver and titanium alloy or steel segments. The concentration of Silver ranged from 0% to 100%. The layers properties as silver content, structure, adhesion, and antibacterial properties (Gram-positive Bacilus subtilis) were measured. Film adhesion was studied using scratch test. The antibacterial efficacy changed with silver dopation up to 99.9%. Our investigation focused on minimum Ag concentration needed to reach a high antibacterial efficiency, high film adhesion and hardness.
