Antibacterial Activity of Passiflora incarnata Mediated Zinc Oxide Nanoparticles Against Listeria monocytogenes

ABSTRACT

Plant-mediated nanoparticle synthesis research is a rapidly growing field. In this study, Passiflora incarnata L. leaf extract was used to biosynthesize ZnO-NPs using environmentally friendly approach. UV-Visible spectroscopy (UV-Vis), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and dynamic light scattering (DLS) were used to characterize the prepared ZnO-NPs. Listeria monocytogenes was used to assess the antibacterial activity. The SEM results showed that rectangular-shaped ZnO-NPs with an average particle size of 212nm (with a size range of 80 -315nm) was prepared. It showed good antibacterial activity against Listeria monocytogenes. ZnO-NPs prepared from Passiflora incarnata leaf extract has the potential to be an effective antibacterial treatment for Listeria monocytogenes-related foodborne illnesses. However, to learn how it affects the intended microorganism, more investigation is required.
