عنوان انگلیسی Superparamagnetic Nanoparticles Doped with Lanthanum by Electrochemical Method for Biomedical Applications
چکیده انگلیسی مقاله In this paper, well-distributed Lanthanum-doped Superparamagnetic nanoparticles (La-Fe3O4) are reported. Nanoparticles powder has been synthesized using cathodic electrochemical deposition method. By applying a constant current density of 1 A in a two-electrode electrochemical system, nanoparticles with a diameter of approximately 11 nm with a spherical structure were prepared. The structure, morphology and magnetic properties of these nanoparticles have been systematically investigated by using TEM, XRD, VSM and FT-IR analysis. The results indicate the existence of a superparamagnetic behavior at room temperature for progressive measurements as a function of the magnetic field. The magnetic hysteresis (magnetic saturation, Coercivity and Remanence) of the sample shows the effective role of doped lanthanum in improving the magnetic properties of ferrite nanoparticles, and the magnetic saturation value is 54.23 emu/g. Based on these results, the electrochemical method can be used as an efficient and low-cost synthetic method to make iron oxide nanoparticles doped with lanthanum.
