Bioactivation of Titanium Surfaces by Femtosecond laser Processing

The primary objective of current orthopaedic biomaterials research is to design implants that can stimulate guided, controlled, and rapid healing. In the present study, we propose a novel method to tailor titanium surfaces by synthesizing 3D titanium oxide nanofibrous structures using femtosecond laser processing. The bioactivity of the Ti surface is evaluated by simulated body fluid (SBF). Our results show that the synthesized nanofibrous structures significantly promote the apatite ability of the titanium surfaces. The synthesized 3D nanofibrous structures could advance titanium interfacial properties to improve cell-implant surface interaction and develop new functional biomaterials.
