With magnetization saturation roughly twice that of iron oxide nanoparticles, metallic iron nanoparticles (also termed zero-valent iron nanoparticles) have desirable properties for use as a magnetic resonance imagining (MRI) contrast agent as well as a medium for hyperthermia treatment of cancer. Metallic iron nanoparticles, however, are difficult to synthesize and maintain due to their high degree of reactivity and proclivity for oxidation. The main goal of this study was to investigate how ambient oxidation affects the chemical composition and structural properties of metallic iron nanoparticles initially synthesized through a facile reduction reaction of iron (III) chloride with sodium borohydride.
