Laser ablation of biocompatible Ti6Al4V for bio-medical applications

The ns pulse laser ablation of Ti6Al4V alloy was investigated to prepare thin biocompatible films deposited on different substrates in vacuum and nanoparticles (NPs) in biological liquids. Thin films and solutions with NPs were characterized using different physical approaches. Measurements of ablation yield versus laser fluence, solution properties, nanoparticles investigation, optical spectroscopies, plasma characteristics, and others were presented. A particular study focused on the stoichiometry of the ablated material in relation to the pristine target is presented. The possible applications of the produced thin film, synthesized nanoparticles, and obtained solutions are discussed.
