Effect of chemically synthesis compared to biosynthesized ZnO nanoparticles using aqueous extract of C. halicacabum and their antibacterial activity

Abstract

In the present work, chemically synthesis compared to Biosynthesized ZnO NPS using aqueous extract of C. halicacabum (0.2, 0.4, and 0.6 mL) for various concentrations. Influence of the synthesized products were characterized by Ultra violet–Vis spectroscopy, Photoluminescence, Dynamic light scattering analysis, Zeta potential study, X-ray diffraction, Fourier transform infrared, Scanning electron microscopy and anti-bacterial activities, respectively, UV–visible spectrometry study revealed surface plasmon resonance at 387 nm, Dynamic light scattering analysis shows average particle size of 48 nm whereas zeta potential value confirms the stability of formed zinc oxide nanoparticles, The XRD patterns show the cubic phase and average particle sizes are 65, 62, 55, and 48 nm, The functional groups and band area of the samples were established by FT-IR spectroscopy the presence of both leaf extract and ZnO NPs. The surface morphologies analysis has been hexagonal quartzite structure confirmed from SEM. Finally antibacterial activities against Gram-positive and negative bacteria. The good antibacterial activities of Gram negative bacteria. The present Bio -ZnO NPs nanoparticles suggests that have the great potential applications on various industrial and medical fields of research.
