microRNA is an endogenous non-coding single-stranded RNA with a length of about 18~24 nucleotides. The latest research has found that the occurrence of many diseases and tumors is closely related to the level of microRNA expression, and microRNA is expected to become a new tumor marker and a new target for cancer treatment. Therefore, the development of high sensitivity, high specificity, and simple and rapid microRNA detection methods is greatly significant for biomedical research and early diagnosis of cancer. Surface-enhanced Raman spectroscopy (SERS) technique has great application value in the field of early cancer diagnosis due to its unique advantages such as high sensitivity, fast detection speed, fingerprint recognition, and low water interference. The latest research progress of SERS technique in microRNA detection is summarized in this review. Finally the main challenges of SERS technique in bioassay are discussed and the future development trend is proposed.

Key words: surface-enhanced Raman spectroscopy, microRNA, tumor marker
