AbstractIron oxide nanoparticles have been reported to be widely used in many biological applications such as magnetic resonance imaging, anticancer agents, contrast enhancement, tissue repair, and detoxification of biological fluids. The nanoscale size of the iron oxide particles synthesized for use in such applications gives them super magnetic properties. Arc discharge method is one of the simplest methods to be used in nanoparticle production in terms of both feasibility and efficient results. Therefore, arc discharge method has been used in the synthesis of iron oxide nanoparticles for use in such applications. In this method, which simply consists of an anode, cathode and a power source, tungsten electrodes were used to obtain iron oxide nanoparticles. The cathode was drilled and filled with iron powder. The synthesis was carried out in deionize water under 50A DC current and 30V. The synthesized powders were characterized by fourier transform infrared spectroscopy (FTIR), transmission electron microscope (TEM), scanning electron microscope (SEM) electron dispersive X-ray analysis (EDX).
