Green synthesis of zinc oxide nanoparticles (ZnO-NPs) using Ailanthus altissima fruit extracts and antibacterial activity

Abstract

Green synthesis of zinc oxide nanoparticles (ZnO-NPs) using Ailanthus altissima fruits aqueous extract. Recently, the green synthesis of zinc oxide nanoparticles have been a keen interest amongst researchers and scientist due to its simplicity eco-friendliness, non-toxic, inexpensive and potential to perform in antibacterial activity. Thus, in this current work, the synthesis of zinc oxide nanoparticles using Ailanthus altissima fruits aqueous extract is reported. The green synthesized zinc oxide nanoparticles were characterized using scanning electron microscope (SEM), UV-Vis absorption spectroscopy and X-ray diffraction (XRD). The average size of the nanoparticles prepared was found to be ranging from 5 to 18 nm. The FT–IR analysis suggests that the obtained ZnO-NPs have been stabilized through the interactions of flavonoids, and phenolic compounds in the fruits extract. Synthesized ZnO-NPs reveals antibacterial activity against two bacterial strains, Escherichia coli and Staphylococcus aureus. It is concluded that the ZnO-NPs have high efficient antibacterial activity and considered as a potential additive to substitute toxic chemical and physical antibacterial materials.
