英文摘要:

      Surface enhanced Raman scattering (SERS) spectroscopy is a highly sensitive analytical technology for detecting interfacial properties, intermolecular interactions and molecular structures. In recent years, this detection technique has been widely used in pesticide residue detection, in which strengthening the substrates play an important role. This study analyzed the advantages and disadvantages of enhanced substrates preparation methods, and reviewed application of SERS in pesticide residue detection. The development direction of surface enhanced Raman spectroscopy in pesticide residue detection will be to select the strengthened substrate with high stability, combine the sample pretreatment technology with other spectral technologies, improve the detection efficiency of pesticide residue, and improve the detection accuracy and sensitivity.
