A REVIEW ON ECO-FRIENDLY APPROACH FOR GREEN SYNTHESIS OF ZINC OXIDE NANOPARTICLES USING PLANT LEAF EXTRACTS

Abstract

Nanotechnology is concerned with the development and applications of nanoscale materials. Nanoparticles have a high surface area to volume ratio and thus have very unique properties due to their nanoscale dimension. Due to the abundance of zinc and the relatively simple conversion of its oxide to nanostructures, ZnO-based nanomaterials are of great use for many leading applications since the beginning of nanoscience. Zinc oxide nanoparticles (ZnO NPs) have gained a lot of attention because of their wide bandwidth and strong exciton binding energy, and possess antibacterial, antifungal, anti-diabetic, anti-inflammatory, wound healing, antioxidant, and optical properties. Because of its versatility, eco-friendliness, and comprehensive biological activity, plant-mediated green synthesis of nano-metal oxide particles is gaining a lot of traction as a viable alternative to not only physical but also chemical processes, avoiding the use of harmful chemicals and harsh environments. This review article is a study of the green synthesis of Zinc oxide nanoparticles (ZnO NPs) using different plant leaf extract.
