Controllable fabrication and sensitive detection based on SERS substrates with Au nanocubes coated Fe3O4

Au nanocubes (NCs) coated Fe3O4 nanoparticles (Fe3O4/Au NPs) were designed and fabricated controllably via a facile method. The diameter of Au NCs in the surface of Fe3O4 was 65 nm, considering the appropriate size for Au NPs as surface-enhanced Raman scattering (SERS) substrates, which makes the Fe3O4/Au NPs used for pesticide analysis with high sensitivity.
