Title: In-vitro study of copper doped SiO{sub 2}-CaO-P{sub 2}O{sub 5} system for bioactivity and antimicrobial properties

Samples of the xCuO-(45-x)CaO-10P{sub 2}O{sub 5}-45SiO{sub 2} system (x varies from 0 to 4 mole%) have been synthesized for application as biomaterials to slow or inhibit the growth of living organisms (fungi and other pathogenic microorganisms) by the combination of sol-gel and co-precipitation processes. Prepared samples have been characterized by X-Ray Diffraction, Fourier Transform Infra-Red and Field Emission Scanning Electron Microscopy techniques before and after immersion in simulated body fluid. Antimicrobial activity of samples has been investigated against Staphylococcus aureus. Releasing of Cu{sup 2+}and other ions in the simulated body fluid has been determined by Atomic Absorption Spectroscopy to ensure the use of prepared material as biomaterial with good antibacterial properties.
