Iron oxides can be synthesized

All known wet chemical methods can synthesize iron oxides, but tailoring the particle size to the nano range and the morphology toward a particular application remains challenging. Iron oxides, either Fe3O4 or γ-Fe2O3, can be prepared from aqueous Fe2+/Fe3+ salt solutions by adding a base under an inert atmosphere at room temperature or elevated temperature (Bee et al., 1995). A thermal decomposition method has been developed as an effective way to synthesize high-quality semiconductor and oxide nanoparticles with controlled size and shape. This method decomposes organometallic compounds as precursors in high-boiling nonaqueous media containing stabilizing surfactants (Sun et al., 2004; Park et al., 2004; Redl et al., 2004; O'Brien et al., 2001). Iron oxide nanoparticles with a high level of monodispersity and size control were obtained by high-temperature decomposition of organic iron precursors, such as Fe(Cup)3, Fe(CO)5, or iron(III) acetylacetonate [Fe(acac)3], using organic solvents and surfactants (Hyeon et al., 2001). Other methods, including microemulsion, hydrothermal, and sol-gel, have also been investigated to synthesize magnetic nanoparticles. Several phase transfer strategies have been applied to hydrophobic magnetic nanoparticles to obtain the aqueous dispersion necessary for biomedical applications (Deng et al., 2005; Del Monte et al., 1997; Kim & Kim, 2006; Yu et al., 2006; Qin et al., 2007).
