Abstrakt: This work presents the synthesis of bioactive glass 55SiO2– 41CaO– 4P2O5(mol%) by the hydrothermal method using oleic acid as a structural-control agent. Glass samples synthesized at different oleic acid concentrations 0 M, 0.25 M, 0.5 M, and 1 M (denoted as 55 S-0 M, 55 S-0.25 M, 55 S-0.5 M, 55 S-1 M) were characterized by physic-chemical methods such as TGA-DCS, XRD, FTIR, SEM, TEM, and BET. According to the findings, glass materials in the form of amorphous and mesoporous structures can be synthesized by heating dried gel at about 700 oC. The formation of sharp hydroxyapatite peaks after in vitro experiment shows higher bioactivity in samples 55 S-0.25 M, and 55 S-0.5 M, which have higher porosity, and specific surface area. Furthermore, all glass samples synthesized in oleic acid demonstrate excellent biocompatibility with fibroblast cells (L-929).
