Evaluation of anti-bacterial and rice seed germination potential of green and chemically synthesized ZnO nanoparticles

Abstract

The present study focus on evaluation of the seed germination as a agricultural important, by green synthesizes and (poly vinyl alcohol coated ZnO nanoparticles) chemical synthesis using co-precipitation method using urea as a reducing agent, its characterization has been done by various instrumental techniques. Synthesized ZnO nanoparticles were characterized by UV–Vis spectroscopy depicted the absorption peak around 350 nm which indicates that ZnO nanoparticles displays excitant absorption due to their large excitant binding energy at room temperature. The main functional groups responsible for reduction reaction which were presented in the sample were identified by Fourier Transform infrared spectroscopy, the crystalline structure and d-spacing of ZnO nanoparticles has been confirmed with “X-ray diffraction studies”. The average crystalline size of particles found to be 51 nm using Debye Scherer formulae. Scanning electron microscopy and atomic force microscopy were used for evaluate the morphology and particle size of ZnO nanoparticles and found that the particle size of nanoparticles are between 2 nm to 10 nm. The elemental signals of Energy dispersive spectroscopy analysis was confirmed the presence of Zn, O elements. Seed germination properties of synthesized ZnO nanoparticles have been successfully tested with different concentration as it is agriculturally essential element for development of high crop yields.
