Enhancement of bioactive glass biocompatibility by deposition of titanium nanofibres generated by the High Intensity Laser Induced Reverse Transfer Method (HILIRT)

Abstract

A literature review was done in order to understand the structure and properties of the surface of bioactive glass and how to make this structure biocompatible with the human body. In this research, glass biocompatibility was increased using a deposition method called high intensity laser induced reverse transfer (HILIRT), and the samples were utilized as enhanced-biocompatibility bioactive glass (EBBG) with a correspondent nanofibrous titanium (NFTi) coating. HILIRT is an ultrafast laser method for improving implants for biomedical applications and provides a thin film of NFTi on the glass substrate. The proposed method in which NFTi samples with different structures are synthesized at various laser parameters such as power, frequency and pulse duration does not have any of the disadvantages of conventional methods such as etching. Physical properties, cell compatibility and adhesion of these NFTi prepared with different laser parameters before and after immersion in simulated body fluid (SBF) were compared.
