以含铁和钆的多核配合物为单源前驱体合成了钆掺杂的磁铁矿纳米颗粒（Gd：Fe 3 O 4）。该合成产生具有在2摩尔%范围内的钆含量的良好限定的八面体颗粒（12.6 +/-2.6 nm直径）。在低幅射频磁场激发下，纳米颗粒的比吸收率为3.7 +/- 0.6 W g（Fe）（-1），具有中等的生物相容性，表明这些颗粒是磁热疗应用的可行候选物。
An iron and gadolinium-containing bimetallic polynuclear complex was used as a single source precursor in the synthesis of gadolinium-doped magnetite nanoparticles (Gd:Fe3O4). The synthesis produces well defined octahedral particles (12.6 +/- 2.6 nm diameter) with a gadolinium content in the region of 2 mol%. The nanoparticles showed a value of the specific absorption rate of 3.7 +/- 0.6 W g(Fe)(-1) under low-amplitude radiofrequency magnetic field excitation, and moderate biocompatibility, suggesting that these particles are viable candidates for magnetic hyperthermia applications.
