英文摘要 | MicroRNAs (miRNAs) play significant regulatory roles in physiologic and pathologic processes and are considered as important biomarkers for disease diagnostics and therapeutics. Simple, fast, sensitive, and selective detection of miRNAs, however, is challenged by their short length, low abundance, susceptibility to degradation, and homogenous sequence. Here, we report a novel design of nanoprobes for highly sensitive and selective detection of miRNAs based on MoSrloaded molecular beacons (MBs) and duplex-specific nuclease (DSN)-mediated signal amplification (DSNMSA). We show that MoS, nanosheets not only exhibit high affinity toward MBs but also act as an efficient quencher for absorbed MBs. The strong fluorescence-quenching ability of MoS2 in combination with cyclic DSNMSA contributes to the superior sensitivity of our method, with a limit of detection 4 orders of magnitude lower than that of traditional hybridization methods. Moreover, the nanoprobes also show high selectivity for discriminating homogenous miRNA sequences with one-base differences because of the discrimination ability of MBs and DSN. Furthermore, we demonstrate that the MoS2-loaded MB nanoprobes can be utilized for multiplexed detection of miRNAs. Given its high sensitivity and specificity, as well as the multiplexed function; this novel method as an effective tool shows a great promise for simultaneous quantitative analysis of multiple miRNAs in biomedical research and clinical diagnosis. |
