Biosynthesis of Zinc Oxide Nanoparticles using Euphorbia Milii Leaf Extract- A Green Approach

Abstract

In the past few decades, nanomaterials have demonstrated superior performance in numerous applications, including medicine, energy, and advanced manufacturing. However, many of the materials and processes currently used are not only dependent on nonrenewable resources but also create hazardous wastes. Green nanotechnology, the combination of nanotechnology and green chemistry, may hold the key to building an environmentally sustainable society in the twenty-first century. Nature provides us with numerous chemical substances that serve as suitable reducing agents for the synthesis of nanoparticles, including plant extracts, biopolymers, vitamins, proteins, peptides (e.g., glutathione), and sugars (e.g., glucose, fructose). Plant extracts are the most studied category to date. Given their abundance, plant extracts are regarded as one of the most promising natural reducing agents. One area of particular success is the synthesis of metal nanoparticles, useful in electronics and medical applications, using plant extracts as reducing agents. Among all metal nanopartilcles, Zinc oxide nanoparticles have received considerable attention due to their unique antibacterial, antifungal, UV filtering properties, high catalytic and photochemical activity. The present study focus on green synthesis of Zinc Oxide nanoparticles by Zinc acetate and utilizing the bio components of leaves extract of Euphorbia milii. Formation of zinc oxide nanoparticles have been characterized by UV-Vis absorption spectroscopy, X-ray diffraction (XRD), Dynamic Light Scattering (DLS), scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDX) and stability of the nanoparticles were analysed by zeta potential analysis.
