Synthesis of SiO₂ and CaO rich calcium silicate systems via sol-gel process: bioactivity, biocompatibility, and drug delivery tests.


Silica and calcium silicate amorphous materials, mixed with sodium ampicillin, a broad-spectrum antibiotic, have been synthesized by sol-gel method. The amorphous nature of the gels was ascertained by X-ray diffraction analysis. The bioactivity of the synthesized materials has been put into evidence by the appearance of a crystal of hydroxyapatite on the… (More)
