We report,a facile synthesis of body centered cubic (bcc) Fe nanoparticles (NPs) via the thermal decomposition of iron pentacarbonyl, Fe(CO)(5), in the presence of hexadecylammonium chloride. These bcc-Fe NPs exhibit a drastically increased stability and magnetic moment (M-s = 164 A . m(2) . kg(-1) (Fe)) even in physiological solutions, and have much enhanced magnetic imaging contrast (r(2) = 220 s(-1) . mM(-1)) and heating (SAR = 140 W . g(Fe)(-1)) effects. They may serve as robust probes for imaging and therapeutic applications.
