Electrochemical interrogation of conformational changes as a reagentless method for the sequence-specific detection of DNA

We report a strategy for the reagentless transduction of DNA hybridization into a readily detectable electrochemical signal by means of a conformational change analogous to the optical molecular beacon approach. The strategy involves an electroactive, ferrocene-tagged DNA stem–loop structure that se...
