    Voltammetric determination of DNA based on regulation of DNA strand displacement using an allosteric DNA toehold

    An electrochemical biosensor for determination of DNA is described that is based on the reaction of regulated DNA (reg-DNA) first with substrated DNA (subs-DNA) to form a reaction intermediate. The intermediat...
