Green synthesis, characterization and antibacterial studies of CuO nanoparticles from Eichhornia crassipes

Abstract

Green synthesis of metal and metal oxide nanoparticles using plants is a predominantly focused research area. In the present work, the CuO nanoparticle synthesis was carried out by a versatile technique from Eichhornia crassipes leaf extract using NaOH. The synthesized particles were characterized with U-V Visible absorption spectra, X-Ray Diffraction analysis (XRD), Fourier Transform infrared spectroscopy (FTIR), Energy Dispersive X-ray spectroscopy (EDX), and Scanning Electron Microscopy (SEM) analysis. The size of the synthesized nanoparticles was obtained to be 20 ± 2 nm and the particle shows excellent antibacterial activity for the pathogens like Staphylococcus pneumonia, Streptococcus aureus, and Klebsiella pneumonia.
