This work reports a synthesis of monodisperse core-shell Fe 3 O 4 @Au nanostructures. Fe 3 O 4 (~4.9 nm) and core-shell Fe 3 O 4 @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 Fe 3 O 4 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 Fe 3 O 4 NP and Fe 3 O 4 @AuNP.
