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(-1)(Fe)) effects. They may serve as robust probes for imaging and therapeutic applications.
我们报告了一种通过在十六烷基氯化铵存在下热分解五羰基铁（Fe(CO)(5)）来合成体心立方（bcc）Fe 纳米粒子（NPs）的简便方法。这些 bcc-Fe NPs 即使在生理溶液中也表现出显著提高的稳定性和磁矩（M(s) = 164 A·m(2)·kg(-1)(Fe)），并且具有增强的磁共振成像对比度（r(2) = 220 s(-1)·mM(-1)）和加热（SAR = 140 W·g(-1)(Fe)）效果。它们可用作成像和治疗应用的强大探针。
