The Effect of Ligands on FePt–Fe3O4 Core–Shell Magnetic Nanoparticles
Abstract
FePt–Fe3O4 core–shell nanoparticles functionalized with 3,4-dihydroxyphenylacetic acid (DOPAC) and dimercaptosuccinic acid (DMSA) ligands were synthesized and characterized. We also found that the DOPAC ligand enhances the magnetic properties of the FePt–Fe3O4 particles, in comparison with the DMSA ligand, which induces the oxidation of the shell layer that causes a significant reduction of the saturation magnetization. We evaluated the synthesized magnetic nanoparticles for applications in magnetic hyperthermia and magnetic resonance imaging contrast enhancement.
