Abstract
Laser-induced breakdown spectroscopy (LIBS) is applied to characterize the formation of porous hydroxyapatite layers on the surface of 0.8CaSiO3-0.2Ca3(PO4)2 biocompatible eutectic glass immersed in simulated body fluid (SBF). Compositional and structural characterization analyses were also conducted by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), and micro-Raman spectroscopy.
Highlights
A new era for tissue engineering has emerged since the discovery of a bioactive glass by Hench et al in 1970 [1]
We report on the characterization of the hydroxyapatite porous layer developed on the surface of the W-tricalcium phosphate (TCP) eutectic glass after being immersed in simulated body fluid (SBF) by using the laser-induced breakdown spectroscopy (LIBS) technique that is based on the generation of micro-plasma and emission spectroscopy measurements

Summary
A new era for tissue engineering has emerged since the discovery of a bioactive glass by Hench et al in 1970 [1]. Silicon and silicon calcium phosphate materials have attracted scientist’s attention for being used as scaffolds in orthopaedic, oral, and maxillofacial applications These materials, during exposure to simulated body fluid (SBF), develop a hydroxyapatite (HA) layer on their surface [2]. To enhance the ingrowth and the bioactivity of the ceramic implant, a suitable interconnected porous structure network is commonly utilized, which provides a higher bioactivity rate and improves both the anchoring of the prosthesis and the blood and nutrition supply for the ingrowth of the new bone [4,5,6,7]. A novel path to accomplish in situ interconnected pore networks has been developed departing from dense bioactive and resorbable eutectic glass-ceramic and glasses of the CaO-SiO2 -P2 O5 and
