Acalypha fruticosa L. leaf extract mediated synthesis of ZnO nanoparticles: Characterization and antimicrobial activities

Today, green synthesized nanoparticles have derived attention due to their unique properties such as low cost and eco-friendly nature. We, for the first time green synthesized ZnO nanoparticles using Acalypha fruticosa leaf extracts and were characterized by UV-Visible spectroscopy, X-ray Diffraction, Fourier Transfer Infrared Spectroscopy, High Resolution Scanning Electron Microscopy, Energy Dispersive Analysis of X-ray, Atomic Force Microscopy, and Transmission Electron Microscopy. Further the biosynthesized nanoparticles were tested against pathogenic microorganisms using agar well diffusion method. In addition, Minimum inhibitory concentration (MIC), Minimum bactericidal and fungicidal concentration (MBC /MFC) were also studied. Thus, this present study concluded that ZnO nanoparticles exhibited potential antimicrobial activity when compared with plant extracts and standard drug. (C) 2019 Elsevier Ltd.
