Silver-Doped Strontium Calcium Silicate Microspheres: Structural and Antibacterial Studies

摘要

Silver doped strontium calcium silicate amorphous microspheres were synthesized via a simple sol-gel method. The morphological and microstructural properties of the materials were investigated through electron microscope with selected area electron diffraction pattern, Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (XRD) methods. XRD and electron microscopy studies clearly reveal the amorphous nature of the samples with micron-sized spheres. FTIR shows the possible vibrations of silicate groups. Antibacterial effects of the sample were investigated with various microbiles by using agar well diffusion method. Incubation zones against E-coli and S aureus are found to be 19 and 19.3 mm respectively.Bone like apatite formation is also found on the surface of the sample through in-vitro studies.
