Plant Based Synthesis of ZnO Nanoparticles and Characterization by UV-Vis Spectroscopy

In the modern fast changing world, as the green and environment friendly methods are much required and preferred over conventional toxic methods, plant based nano synthesis plays a vital role in future developments of nanotechnology. In this research article, we discussed on the synthesis and characterization of Zinc Oxide nanoparticles by green synthesis method utilizing the leaves of Ocimum Tenuiflorum as reducing agent for Zn salt. ZnO NPs prepared by such a technique exhibit superior antibacterial efficacy against a range of bacteria compared to ZnO NPs produced through chemical methods, without developing resistance to antibiotics. Further the prepared ZnO NPs were characterized by UV-Vis spectroscopy technique and the bandgap of particles was calculated by Tauc Plot method.
