Abstract

Mesoporous bioactive glass (BG) nanoparticles based in the system: SiO2–P2O5-CaO-MnO were synthesized via a modified Stöber process at various concentrations of Mn (0-7 mol%). The synthesized manganese-doped BG nanoparticles were characterized in terms of morphology, composition, in vitro bioactivity and antibacterial activity. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET) analysis confirmed that the particles had spherical morphology (mean particle size: 110 nm) with disordered mesoporous structure. Energy dispersive X-ray spectroscopy (EDX) confirmed the presence of Mn, Ca, Si and P in the synthesized Mn-doped BG particles. Moreover, X-ray diffraction (XRD) analysis has shown that Mn has been incorporated into the amorphous silica network (bioactive glass). More over, it was found that manganese-doped BG particles form apatite crystals upon being immersed in simulated body fluid (SBF). Inductively coupled plasma atomic emission spectroscopy (ICP-OES) measurements confirmed that Mn is released in a sustained mannerBacillus subtilis , Pseudomonas aeruginosaaeruginosa Staphylococcus aureus . The multifunctional BG nanoparticles for bone tissue engineering. The results indicate that the incorporation of Mn into the bioactive glass network is effective. and
