heal.abstractMagnetic bioglasses in the system CaO-SiO(2)-P(2)O(5) were prepared by interaction of acetic acid vapors with iron nitrate dispersed on the surface of sol-gel derived porous silicate network. Upon pyrolysis, the created iron acetate species transform into magnetic iron oxide nanoparticles. X-ray diffraction (XRD), FT-infrared (FT-IR) spectroscopy and surface area measurements (BET) were employed to monitor the evolution of glass structural features during the synthetic pathway as well as the structure and the texture of the resultant glasses. XRD, Raman spectroscopy and vibration magnetic measurements (VSM) revealed the features of magnetic phases, developed in the form of gamma-Fe(2)O(3) and magnetite. The obtained glasses exhibit in vitro bioactivity, expressed by spontaneous formation of hydroxyapatite on their surface after immersion in SBF at 37 degrees C, confirmed with mu-Raman and FT-IR spectroscopies.en
