Typically, an approach of combined two-step thermal decomposition process can continuously synthesize from cores to shells, resulting in the formation of Au-coated magnetic nanoparticles with a high monodispersity. In particular, the Au shell-coated magnetic nanoparticles have widely been studied in order to provide not only the surface plasmon properties but also a reactive surface for strong binding to organic compounds containing thiol groups. Magnetic nanoparticles with a core/shell structure have attracted a great deal of attention due to their multifunctionality including optical, electronic, and magnetic properties. Although many different chemical methods have been developed to fabricate CoFe2O4 nanoparticles, the thermal decomposition method has recently been employed one of the most promising procedures to obtain highly, structurally, and morphologically controlled nanoparticles with a high crystallinity. Particularly, cobalt ferrite (CoFe 2O 4) nanoparticles have a large maximum coercive field ( H c), even with a small size as well as a remarkable chemical stability and a mechanical hardness. Īmong the magnetic nanoparticles, a spinel ferrite nanoparticle has frequently been employed as a magnetic core because of its excellent magnetic and electrical properties. Over the last decade, magnetic nanoparticles with a core/shell structure have gained a lot of attention in a wide range of fields from engineering to medical sciences owing to the applications of magnetic fluids, magnetic separation, recoverable catalysts, drug delivery system, and an enhanced magnetic resonance imaging (MRI) contrast agents.
