Abstract:

      Surface enhanced Raman spectroscopy(SERS) technique has attracted the attention from analysts due to its advantage of potential capability for on-site rapid analysis and so on.However£¬the SERS signals would be easily influenced by the complex sample matrixes during real analytical processes£¬acquiring poor reproducibility.Thus£¬SERS technique is mostly used in qualitative or semi-quantitative analysis projects at present£¬and reliable SERS quantitative analysis technique still remains to be improved.With the continuous development of science and technology£¬an increased demand of people for more accurate surface enhanced Raman quantitative techniques is developed.Herein£¬the research progress of currently popular SERS quantitative analysis techniques is reviewed£¬including external standard methods£¬internal standard methods and chemometrics quantitative methods£¬in recent years.In addition£¬the development trend of SERS quantitative analysis technology is prospected in the future.
