摘要
综述了最新发展的MicroRNA(miRNA)分析方法,包括比色、荧光、化学发光、表面增强拉曼、单分子检测和电化学分析,并对miRNA检测的发展方向做了展望.
MicroRNA （miRNA） is a class of endogenous noncoding RNA molecule with the length of about 22 nucleotides. MicroRNA may regulate more than 50% of human protein-coding genes, and plays important roles in regulating cell differentiation and other biological processes. The abnormal expression of miRNA is closely related to the occurrence of many diseases including cancers. Therefore, miRNA may function as a potential biomarker for molecular diagnostics. The sensitive detection of miRNA is essential to the early clinical diagnosis and the development of anticancer drugs. Because of the short size, low abundance in total RNA samples and the homologous similarities in miRNA family, the ultrasensitive detection of miRNA remains a great challenge. Recently, many new methods have been developed to improve the detection sensitivity. This review focuses on the advance in miRNA detection methods including colorimetric assay, fluorescent assay, ehemiluminescent assay, surface enhanced Raman scattering, single molecules detection and electrochemical detection. In addition, we give a new insight into future development of miRNA assay.
