Synthesis, characteristics and antimicrobial activity of ZnO nanoparticles

• The XRD pattern confirmed the crystalline nature of ZnO nanoparticles.
• FTIR pattern revealed the presence of ZnO bonding and the functional groups responsible for reduction of ZnO nanoparticles.
• Structural morphology of ZnO nanoparticles was studied by SEM analysis.
• EDX analysis revealed the chemical composition and purity of synthesised ZnO nano particle.
• The ZnO nanoparticles exhibited efficient antimicrobial activity.

The utilization of various plant resources for the bio synthesis of metallic nano particles is called green technology and it does not utilize any harmful protocols. Present study focuses on the green synthesis of ZnO nano particles by Zinc Carbonate and utilizing the bio-components of powder extract of dry ginger rhizome (Zingiber officinale). The ZnO nano crystallites of average size range of 23–26 nm have been synthesized by rapid, simple and eco friendly method. Zinc oxide nano particles were characterized by using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray spectroscopy (EDX). FTIR spectra confirmed the adsorption of surfactant molecules at the surface of ZnO nanoparticles and the presence of ZnO bonding. Antimicrobial activity of ZnO nano particles was done by well diffusion method against pathogenic organisms like Klebsiella pneumonia, Staphylococcus aureus and Candida albicans and Penicillium notatum. It is observed that the ZnO synthesized in the process has the efficient antimicrobial activity.
