---------------------------------------------------------------------------***--------------------------------------------------------------------------ABSTRACT Iron oxide has attracted a great deal of attention among specialists because of their multivalent oxidation states. The iron oxide nanoparticles have been synthesized by adding Albizia Amara leaf extract into the aqueous solution of ferric chloride. The phytoconstituents of A. Amara leaf extract serve a dual role as reducing, capping and stabilizing agent during the synthesis. GSIron Oxide nanoparticles were characterized by UV-vis absorption Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD) and Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM). The existence of the Fe2O3 nanoparticles was revealed by UV-vis spectroscopy. The FTIR spectra of leaf extract and synthesized Fe 2O3 nanoparticles identifies the functional groups of the active components. The formation of Fe 2O3 nanoparticles has been confirmed by X-ray diffraction and average crystallite size for assign peaks were 37.91 nm. GS- iron oxide nanoparticles serve as potent antibacterial agent in an eco-friendly way by securing naturally biome as nanoparticles usually through target delivery. Thus, A. Amara mediated iron oxide nanoparticles can act as an alternative antimicrobial agent to the antibiotics.

Introduction Nanoparticles are submicron moieties with diameters range starting from 1-100 nm made up of organic or inorganic materials having novel properties as compared to a large number of materials [1]. The nanotechnology process depends on synthesis, manipulation, and use of materials that are of Nano scale size. In the new era, nanoparticles take more attention due to their unique size-dependent properties and applications [2]. Metal nanoparticles gain great attention due to their wide range of applications in the fields of electronics, optoelectronics, antibacterial activity, and medical applications such as therapy, diagnosis, and drug delivery [3-4]. The development of adequate techniques for synthesizing metal nanoparticles has become a major focus of researchers. Metallic nanomaterial such as silver, gold, zinc and iron are used in various fields because of their broad applications; among these nanoparticles, iron nanoparticle is preferred for the following reasons: cost effective, antimicrobial activity, high reactivity, smaller size; therefore, it gives high surface-area-to-volume ratio, which allows interact with different chemical species and also efficient in binding metal ions [5]. There are a large number of methods (physical, chemical, and biological) to synthesize various types of nanomaterial. When synthesized by chemical and physical methods, these nanoparticles lose their reactivity due to aggregation magnetism, and dispersibility upon air exposure. Chemical synthesis methods involve toxic chemicals, the formation of hazardous by-products, and contamination from chemical precursors [6]. Therefore, there is growing interest in developing clean, simple, inexpensive, eco-friendly methods for the synthesis of nanoparticles. Bacteria, fungi, algae, and plant extracts can be used in modern alternatives for the production of metal/metal oxide nanoparticles. Plant mediated synthesis of nanoparticles is a revolutionary technique that has wide range of applications in agriculture, food industry, medicine and environmental remediation. The plant related parts such as leaves, stems, roots, shoots, flowers, barks, seeds and their metabolites have been successfully used for the efficient biosynthesis of nanoparticles. Plant extracts usually contain sugars, terpenoids, polyphenols, alkaloids, phenolic acids, and protein, which are responsible for reducing and stabilizing metal nanoparticles [7]. In the past, green synthesis of Fe2O3 nanostructures using different plant extracts such as Lagenaria siceraria, Hordeum vulgare and Rumex acetosa plants, peel extract of plantain and Tridax procumbens leaf extract. Therefore, in this study, we have made an attempt on the synthesis of Fe 2O3 nanoparticles using extract of Albizia Amara leaves.
