Abstract

In recent years, magnetic particles have attracted attention in the scientific field for their potential applications in biomedical topics. Fe2O3–Al2O3 magnetic particles were obtained by sol–gel synthesis at three-atmosphere conditions. The powders were characterized by DSC/TGA, XRD, and SEM. A vibrating sample magnetometer (VSM) evaluated the magnetic behavior of the composite material. 1.5 wt% of the nanoparticles were added to a polycaprolactone matrix to obtain a homogeneous polymeric-magnetic composite thin film with an average thickness of 1.43 μm. The results showed the obtainment of Fe2O3–Al2O3 systems which can be used as magnetic wires for remotion of biomarkers.
