We develop a new fluorescent method for sensitive detection of long noncoding RNAs (lncRNAs) on the basis of duplex-specific nuclease-actuated cyclic enzymatic repairing-mediated signal amplification. This method exhibits high sensitivity with a detection limit of 0.081 fM, and it can accurately detect the endogenous lncRNA HOTAIR in cancer cells, providing a new approach to study the physiological function of lncRNAs in human diseases.
