title: Target recycling amplification for sensitive and label-free impedimetric genosensing based on hairpin DNA and graphene/Au nanocomposites.
abstract: The presence of exonuclease III leads to direct recycling and reuse of the target DNA, which in turn results in substantial signal amplification for highly sensitive, label-free impedimetric detection of specific DNA sequences.
