The continuous hydrothermal synthesis of nanoparticles of two metal oxides (α–Fe2O3 and Co3O4) is described. Two variations of the technique were investigated, involving the precipitation reaction between a metal salt solution and a hydroxide solution at ambient conditions and at elevated temperatures. Elevated temperatures resulted in more uniform particles of α–Fe2O3 and Co3O4, although the actual sizes of the particles were apparently unaffected by the temperature. This behavior was attributed to the species present in solution and the solubilities of the cation(s), both of which were calculated via a thermodynamic model for the systems under study.

Abstract The synthesis, characterization, and applications of iron oxide nanorods have received attention in recent years. Even though there are several studies on the biological applications of iron oxide nanoparticles, recent studies have shown that rod-shaped iron oxides are effective in magnetic hyperthermia (MHT) as therapeutic technique to treat cancer. This review focused on the synthesis and encapsulation of magnetic iron oxide nanorods (MIONRs) and their use in (MHT) and photothermal therapy (PTT) for cancer cells. Among the synthetic methods that have been used to prepare MIONRs, some could be used to precisely control the particle size of the as-prepared magnetic iron oxide nanoparticles (MIONs), while others could be used to prepare monodisperse particles with uniform size distributions. Some of the results presented in this review showed that magnetic oxide nanorods are more potent in MHT than polyhedral-shaped MIONs. The review shows that mixtures of polyhedral- and rod-shaped MIONs resulted in 59 and 77% cell death, while monodisperse MIONRs resulted in 95% cell death. It could thus be concluded that, for magnetic iron oxide to be effective in MHT and PTT, it is important to prepare monodisperse magnetic oxide nanorods.
