•Au nanocubes (NCs) with the size of 65 nm coated Fe3O4 nanoparticles (Fe3O4/Au NPs) were designed and fabricated controllably via a facile method.•The Fe3O4/Au NPs obtained could be used for pesticide analysis with high sensitivity.•It was demonstrated Fe3O4/Au NPs were recyclable under an external magnetic force.
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.
