摘要：

The study of superparamagnetic Fe3O4/Ag nanocomposites have received great research attention due to their wide range of potential applications in biomedicine. In this report, an easy microemulsion reaction was employed to synthesis Fe3O4/Ag nanocomposites with self-aggregated branch like nanostructures. The Fe3O4 nanoparticles were initially prepared and subsequently AgNO3 was reduced as Ag by chemical reduction method. The results showed that the average size of the Fe3O4/Ag nanocomposites were in the range of 10 +/- 2 nm. These nanoparticles were self-aggregated as a branch like nanostructure. The optical properties of Fe3O4 nanoparticles were modified with surface plasmon resonance of Ag nanoparticles. The observed saturation magnetization of superparamagnetic Fe3O4/Ag nanocomposites were 40 emu/g.
