Abstract
Green synthesis of nano-dimensional metal oxide particles are of great importance due to their medicinal and sensing properties. Metal oxide nanostructures have attracted considerable spouting research in many potential limelight fields of biotechnology, chemistry, physics and environmental biotechnology due to their dependent properties of size and shape. In this attempt, the authors synthesized the Magnesium Oxide (MgO) nanoparticles using ethanolic extract of Clitoria ternatea as reducing and capping material. The plasmon resonance of grown nanoparticles by varying different optimal conditions (temperature, amount of extract and pH values) of nanoparticles was investigated by UV-Vis spectroscopy. The size, shape, surface morphology and elemental composition of bio-transformed MgO nanoparticles were characterized by different analytical techniques such as FT-IR, SEM, EDX, PL intensity and XRD analysis. The anti-oxidant activity of biologically synthesized MgO was evaluated by DPPH free radical scavenging activity and reducing power assay. The results showed the 60% inhibition which clearly indicates the antioxidant activity of green synthesized MgO nanoparticles.
