In recent years, nanotechnology has emerged as a start-of-the-art, with multifarious applications in a wide array of fields. Studies on green synthesis of nanoparticles moves forward these days. The present work involves the green method of synthesizing Iron oxide nanoparticles [Fe2O3] by Phyllanthus Niruri leaf extract and NaOH which acts as a precipitating agent. Furthermore, the green synthesized Iron oxide nanoparticles were characterized and its antibacterial activity was investigated. As this plant extract is more beneficial, it is energy efficient, low cost and environmentally friendly process than the biohazardous chemical synthesis. Iron oxide nano particles are gaining importance for their uses in environmental remediation technologies. The characterization of nano particles includes the IR, UV-Vis, and Size determination using SEM and XRD. The average crystalline size of the iron oxide nanoparticles was calculated by Debye’s Scherrer formula,d = 12.34nm. The analytical studies revealed that the synthesized Iron oxide nanoparticles almost have the identical size and morphology. Thus, the above studies concluded, the synthesized material was Iron oxide nanoparticles.

Studies on green synthesis of nanoparticles moves forward a lot on these days. The present work involves the green method of synthesizing iron oxide nanoparticle from Phyllanthus niruri leaf extract. Furthermore, the green synthesized iron oxide nanoparticles were characterized and its antimicrobial activity was investigated. A characteristic comparison with chemical method of synthesis is also done, for iron nanoparticles. The characterization of nanoparticle includes the IR, UV-Vis, surface morphology and size determination using TEM, SEM, and XRD. The analytical studies revealed that the synthesized iron oxide nanoparticles from these two different methods have almost identical size and morphology. The synthesized iron oxide nanoparticles showed significant antimicrobial activity against the microbes, E. coli and P. aeroginosa. The studies concluded that the synthesis of iron oxide nanoparticles using plant extracts is more beneficial as it is an economical, energy efficient, low cost and environment-friendly process than the bio hazardous chemical synthesis. The present investigation may be a definite contribution to green chemistry in general and nano synthesis in particular.

Green approach has received major attention for the synthesis of metal oxide nanoparticles. One such metal oxide nanoparticles are iron oxide nanoparticles (IONPs). IONPs have fetched a great deal of interest in recent era because of their magnetic nature, as they can be easily recovered from the reaction mixture by applying an external magnetic field. Although, a variety of chemical and physical methods of synthesis are known, green synthesis is safer, sustainable and biologically acceptable. Plants and microbes are the main biological materials used for the green synthesis. In present review, the synthesis of IONPs by using plants, bacteria, fungi and algae have been highlighted. IONPs produced by plants, fungi, bacteria and algae usually falls in 1–100 nm range and are of distinct shapes like cubic, tetragonal crystalline, spherical, cylindrical, elliptical, octahedral, orthorhombic, hexagonal rods, nanosphere and quasi spherical. Furthermore, these biomaterials play role of reducing, capping, stabilizing and fabricating agents in green synthesis of nanoparticles. The review put forward a comprehensive report of various routes used for synthesizing IONP, biologically. Intuition into the procedures for synthesis of nanoparticles will help to nourish our learning in the area of nanotechnology.

In every day, new nanoparticles have been synthesized, and their properties have been evaluated since their unique physical and chemical properties, which are very different from the precursors. Nanoscience also has significant advances in obtaining environmentally friendly and sustainable products. Iron oxide nanoparticles, one of the metal oxide nanoparticles, have different forms and properties. In recent years, iron oxide nanoparticles have been successfully synthesized from various plant species using green synthesis pathways and have been analyzed for different bioactivity properties. In this study, iron oxide nanoparticles were synthesized using a completely non-hazardous method using Ficus carica leaf extract. The synthesized product was characterized by SEM, EDX, XRD crystallography, FT-IR, and UV-Vis spectroscopy. Characterization methods have shown that the product was synthesized in mixed form with 43-57 nm size. In addition, the antioxidant activity of the product was analyzed, and it was recorded that the nanoparticle has remarkable antioxidant activity.

Green protocols being eco-friendly and cost effective approach are most widely used for the production of iron oxide nanoparticles using plant-mediated extract of Citrus Sinensis, moreoverbiosynthesized iron oxide (FeO) nanoparticles shows better antibacterial activity.Green synthesis of nanoparticles has been broadly studied from the past few years because of their different features and potential applications in various fields. The successful biosynthesis of iron oxide nanoparticles was confirmed and characterized using UV-Visible spectroscopy, Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR) analysis and Zeta sizer. Antibacterial effect of biologically produced iron oxide nanoparticles was tested against Gram-negative bacteria (Escherichia coli) and Gram-positive bacteria (Macrococus). These results exhibited that iron oxide nanoparticles have high antibacterial potential as these nanoparticles showed significant zone of inhibition against bacteria strains. The proposed green synthesis of iron oxide nanoparticles (NPs) from Citrus Sinensis can be strongly recommended as a potential method for industrial application.
