Summary, etc. <p style="text-align: justify;">Nanoparticles of zinc oxide (ZnO NPs) have been synthesised from naturally available Eggplant, <em>Solanum melongena</em> leaf extract. The methodology has been optimized to obtain ZnO NPs which as are characterized using UV-Visible, X-ray diffraction (XRD), Scanning Electron Microscope (SEM) and FT-Infra red (FTIR) tools to confirm their nano dimensions and chemical properties. The SPR band is obtained at 389 nm in UV-visible absorption spectrum confirmes the formation of ZnO NPs while the presence of -OH, -C-O, -CH<sub>2</sub> and –COO groups at vibrational frequencies of 3500, 105, 3000 and <br /> 1640 cm<sup>-1</sup>, respectively are observed from FTIR. Further, the SEM images show regular flakes like structure, and the average distribution of the nanoparticle is found to be around 100 nm. The newly synthesised ZnO NPs using leaf extract of <em>Solanum melongena</em> show considerable activity against both Gram-negative and Gram-positive bacteria. The ZnO NPs is proved to be more potent against <em>Staphylococcus aureus</em> than <em>E</em>. <em>coli</em>.</p>
