Biosynthesized and Chemically Synthesized Titania Nanoparticles: Comparative Analysis of Antibacterial Activity

Green synthesis of nanoparticles using plant extract is the novel method to develop environmentally benign nanoparticles which can be used in numerous biomedical applications. In this study we have synthesized TiO2 nanoparticles from Titanium Oxysulfate solution using Hibiscus flower extract. The synthesized nanoparticles were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM) and FTIR. The XRD pattern with sharp peaks describes the crystallinity and purity of titanium dioxide nanoparticles. The shape and morphology of TiO2 nanoparticles were studied by SEM analysis, the results clearly represent that the flower extract capped titanium dioxide nanoparticles were dispersed and disaggregated. FTIR spectrum discloses the information about the interaction between the functional groups of the phytochemicals in the flower extract and the TiO2. This report also explains the efficient antibacterial activity of biostabilized TiO2 nanoparticles when compared to chemically synthesized TiO2. Based on the results we confirm that the flower extract stabilized TiO2 nanoparticles may have potential biomedical applications when compared to chemically synthesized TiO2 nanoparticles.
