Laser ablation of biocompatible Ti6Al4V for biomedical applications

Nanosecond pulse laser ablation of Ti6Al4V alloy was investigated for the preparation of thin biocompatible films deposited on different substrates in a 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, NP investigation, optical spectroscopy, plasma characteristics and others are presented. Particular attention was focussed on the stoichiometry of the ablated material in relation to the pristine target. The possible applications of the produced thin film, synthesized NPs and obtained solutions are discussed.
