Abstract:
An autonomous DNA machine recycling the output as the input for isothermal, sensitive, and specific detection of miRNAs has been developed. This machine shows considerably high signal amplification efficiency (∼1000-fold) and thus a low detection limit (∼20 amol). The machine also shows high specificity, discriminating 50 amol of synthetic miRNA from 100-fold larger amounts of its family member and from 100 ng of unrelated total RNAs. Moreover, it is available for practically detecting natural miRNAs in total RNAs.
