Biosynthesis, Characterization and Mechanism of Formation of ZnO Nanoparticles Using Petroselinum Crispum Leaf Extract

Abstract

Aims: The study aimed at synthesizing ZnO NPs using Petroselinum crispum extract, commonly known as parsley, as a source of biosynthesis without utilizing chemical agents for reducing, capping and stabilizing agent. Background: Recently, the biosynthesis of nanoparticles has been widely explored due to the wide range of vital applications in nanotechnology. Biosynthesized zinc oxide nanoparticles, ZnO NPs, have become increasingly important since they have many applications and are environmentally friendly. Methods: The innovation of this investigation is that the nanosized ZnO NPs can be formed from one-pot reaction without utilizing any external stabilizing and reducing agent which is not plausible via the current procedures. Results: The biosynthesized ZnO NPs were characterized using UV-Vis spectroscopy, FT-IR spectroscopy, X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX) to investigate the optical, chemical, structural, and morphological properties. Conclusion: These techniques exhibited that the property of the biosynthesized ZnO NPs is analogous with the standard NPs prepared from dissimilar methods. Investigating the plausible mechanism of formation and stabilization of ZnO NPs by biomolecules of Petroselinum crispum leaf extract was another vital feature of this study.
