A novel 40P2O5–20Na2O–10Ca(OH)2–20CaCl2–6.0ZnO–2.0BaF2–2.0TiO2 (BGBaFTi) bioglasses is prepared. The reaction of the glasses in SBF solution is characterized by XRD and SEM indicated that the carbonate hydroxyapatite has formed rapidly on the glasses. BGBaFTi bioglasses was tested for its antimicrobial activity, anti-proliferative/cytotoxicity against normal and activated splenic cells in vitro and in vivo. This results showed that BGBaFTi has antimicrobial activities against Gram negative and positive bacteria as well as fungi. We found that the antimicrobial activity of nanoparticles of BGBaFTI is high than the normal powder of it. Moreover BGBaFTi (powder and nanoparticle) with cytotoxic effect on normal splenic cells was investigated. The products of activated splenic cells did not cause any changes in the structure of BGBaFTi. It did not cause any acute cytotoxicity or lysis to RBCs which was not affected by lytic products of immune cells. The bioactivity and biocompatibility of the present glasses use it a good potential candidate in the field of tissue engineering.
