Abstract

In this paper, Fe3O4 nanoparticles were prepared by co-precipitation method. And then the spiny Au nanostructures were formed on the surface of Fe3O4 nanoparticles by sodium citrate and hydroquinone reduction of chloroauric acid. The Fe3O4@Au nanostars as Surface-enhanced Raman spectroscopy (SERS) substrate used for thiram pesticide and ediphenphos detection. Due to high-density Au nanotip, the Fe3O4@Au nanostars exhibited high-sensitivity SERS activity. Additionally, this SERS substrate based on Fe3O4@Au nanostars can be found to be recyclable in virtue of the magnetic properties of Fe3O4 nanoparticles.
