摘要
Fe3O4@PDA-Au core–shell satellite nanomaterial as SERS probe integrated the multi-hotspot structure and magnetic separation, thus it can fully load the target molecules and enrich the separation by the applied magnetic field, and then achieve trace detection of eszopiclone and diazepam drugs in serum as low as 1 μg/mL.
