Title: The Effect of Ligands on FePt–Fe 3O4 Core–Shell Magnetic Nanoparticles

FePt–Fe 3O 4 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–Fe 3O 4 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.
