Progress and Trend in Surface-Enhanced Raman Spectroscopy

Surface-enhanced Raman spectroscopy (SERS) which owned the advantages of high detection sensibility and fast analysis speed is a potentially promising tool for sensing molecules in trace amounts.The key to SERS research is the preparation of SERS active substrates, which is stable, has high sensitivity and good reproducibility, the substrates can realize trace analysis. The development of SERS active substrate was reviewed, the applications in some fields were sum-marized, and the problems remaining to be solved were put forward.
