Pulsed laser irradiation (PLI) at different scan rates was used to modify the surface of Ti6Al4V, creating an artificial oxide layer under atmospheric conditions. Analysis of cross sections of samples by focused ion beam revealed that the oxide layers vary in thickness, displaying different colors due to interaction with visible light.
Previous studies have shown the immobilization of antimicrobial peptides (AMP) as a way to confer antibacterial properties to other materials which are prone to biofilm formation; however, subsequent release of AMP from the surface may also contribute to inhibit bacteria in the surrounding medium.
In this study, antibacterial tests demonstrate that Ti6Al4V modified surfaces by PLI and treated with AMP inhibit the growth of Listeria monocytogenes. The response of the surface to mechanical impacts and different environmental conditions (dry, humid, wet, etc.) was evaluated, as well as measurements of the peptide released from the surface.
