Catalyzed Hairpin Assembly

Here, with the target-catalyzed hairpin assembly generated dsDNA (HP1–HP2) to synchronously control the departure of quencher ferrocene and approach of sensitizer methylene blue, a distance-controllable multiple signal amplification based photoelectrochemical biosensor was proposed for MiRNA-21 assay.
