This work reports a synthesis of monodisperse core-shell Fe3O4@Au nanostructures. Fe3O4 (∼4.9 nm) and core-shell Fe3O4@Au (5.0-5.6 nm) nanostructures were successfully synthesized via thermal decomposition method of iron compounds in the presence of oxygen-containing ligands. XRD analysis revealed the pure face-centered cubic (FCC) structure of Fe3O4 with 2 θ peaks at 31 , 38 , 44 and 64 , 77 and 81 attributed to Fe-Au, which can be indexed to lattice planes of gold in a cubic phase. In addition, UV-Vis spectra showed a significant difference absorbance peak between Fe3O4NP and Fe3O4@AuNP.
