Eco-Friendly Synthesis of Magnetic Iron Oxide Nanoparticles Using Achillea Nobilis Extract and Evaluation of Their Antioxidant and Antibacterial properties

Magnetite (Fe3O4) is a magnetic Iron Oxide encountered in many technological applications. The particle size and shape of magnetite nanoparticles allow tuning their properties to different applications such as targeted drug delivery, cancer diagnostic, magnetic resonance imaging, catalysts, pharmaceuticals, biomedicine, and agriculture. During the last two decades, the biosynthesis of nanoparticles has received considerable attention due to the growing need to develop environmentally sociable technologies in nanoparticle synthesis. Therefore, there is a need for the development of an eco-friendly process to synthesize nanoparticles through green chemistry using plants and microorganisms. The research work involves the development of a simple and reliable method for the bio-fabrication of magnetic Iron Oxide nanoparticles (IO-NPS) through the green method using Achillea Nobilis extract. The crystalline structure and morphology of IO-NPS were studied using various characterization techniques i.e. Fourier Transform Infrared Analysis (FTIR), Ultraviolet spectroscopy studies (UV–vis), X-ray diffraction, and FESEM. The antibacterial and antioxidant activity of the iron oxide nanoparticles was determined. Iron Oxide nanoparticles exhibited potent antibacterial activity against gram-positive and gram-negative bacterial strains tested. From the results, this method can be applied to different medical and industrial applications.
