Monodisperse 35 nm FeO nanoparticles (NPs) were synthesized and oxidized in a dry air atmosphere into core/shell FeO/Fe(3)O(4) NPs with both FeO core and Fe(3)O(4) shell dimensions controlled by reaction temperature and time. Temperature-dependent magnetic properties were studied on FeO/Fe(3)O(4)...

Nanomaterials can enhance the delivery and treatment efficiency of anticancer drugs, but the mechanisms of the tumor-reducing activity of ferrous-ferric oxide (Fe(3)O(4)) nanoparticles (NPs) with daunorubicin (DNR) have not been established. Here we investigate the synergistic effects of Fe(3)O(4) NPs...
