title: A reagentless and reusable electrochemical DNA sensor based on target hybridization-induced stem-loop probe formation.
abstract: We report a reagentless and reusable electrochemical DNA sensor that exploits competitive binding and target hybridization-induced change in the signalling probe conformation for robust detection of a target DNA sequence.
