Magnetoferritin is a metalloprotein composed of a protein coat (apoferritin) surrounding the magnetic iron oxide nanoparticles. Physicochemical characterization of magnetic, structural and morphological properties, size distribution and stability of magnetoferritin have been extensively investigated. Magneto-optical properties of magnetic nanoparticles in magnetoferritin can be applied in in vivo diagnosis of various diseases associated with the formation of magnetite in pathological processes in tissues. In addition, the confirmed peroxidase activity enables magnetoferritin to be used in important bioapplications.
