Green synthesis of ZnO nanoparticles using the leaf extract of Lavandula angustifolia and evaluation of their antibacterial activity against human pathogens

The present study was aimed to the biosynthesis of Zinc oxide nanoparticles using leaf extract Lavandula angustifolia. were characterized by different techniques like UV-Visible spectroscopy, FESEM analysis, and X-ray diffraction. From spectra it observed peak obtained at 350 nm confirmed LA-ZnONPs. shape size LA-ZnONPs from analysis found that truncated triangular in with an average 61.52 respectively. Further, XRD showed crystalline nature. By well diffusion assay, antibacterial activity investigated against gram-positive S. aureus (ATCC 25923) gram-negative E. coli 11229) pathogens a dose-dependent manner. exhibited excellent both pathogens. thus possessed human can be used drug development
