摘　　要：金作为一种惰性贵金属,具有生物相容性好,易于功能化等特点,目前已被广泛应用于磁性纳米颗粒的表面的功能化。利用反胶束方法制备了金包铁(Fe/Au)结构的磁性纳米复合颗粒,表征结果显示Fe/Au具有明显的核壳结构,其平均粒径为15 nm。无磁滞现象,其剩余磁化强度与矫顽力均为零。这表明所得的Fe/Au MNPs为超顺磁性颗粒。As an inert metals,Gold has the specialty of good biocompatibility and is immensely suitable to functionalization.It has been widely used in functionalization on the surface of magnetic nanoparticles.In this paper,the Fe/Au magnetic nanoparticles（MNPs） were prepared using reverse micelle method.It was showed that the diameter of the core-shell structure magnetic nanoparticleswas controlled at about 15 nm.There was no hysteresis phenomenon,and both the residual magnetization and the coercive force was zero.The results show that the MNPs had superparamagnetic effect.
