A molecular beacon biosensor for viral RNA detection based on HyCaSD strategy

In the present study, a molecular beacon biosensor was developed to enable efficient detection of the viral RNAs using a previously described HyCaSD platform. The HyCaSD molecular beacon probes were labeled with the Cy5 and BHQ3 at each end of the hairpin probes. The fluorescent signal was detected...
