A New Hydroxyapatite/Glass Biphasic Material:  In Vitro Bioactivity Rámila, Ainhoa Padilla Mondéjar, Sussette Muñoz, Bessy Vallet Regí, María Dulce Nombre A new biphasic material composed of hydroxyapatite and a bioactive glass has been synthesized. The starting materials were hydroxyapatite (HA), synthesized by a wet method, and gel obtained by a sol−gel method with composition in mol %, 55SiO2−41CaO−4P2O5 (55S), both prepared before the mixture. This mixture was performed mechanically and had a final ratio HA/55S glass of 80:20. In vitro assays of bioactivity were carried out to compare the behavior of the three materials. The biphasic material has shown good bioactivity, establishing that the addition of the bioactive glass to the hydroxyapatite accelerates the formation of a hydroxyapatite layer, enhancing the bioactivity of the synthetic HA. 2025-01-31T09:46:43Z 2025-01-31T09:46:43Z 2025-01-31T09:46:43Z 2002 journal article https://hdl.handle.net/20.500.14352/117490 0897-4756 1520-5002 10.1021/cm011165p eng info:eu-repo/grantAgreement/CICYT//MAT 99-0466 Rámila, A., et al. «A New Hydroxyapatite/Glass Biphasic Material: In Vitro Bioactivity».
