(A) Gel electrophoresis analysis of 1 μM hairpin probe (a), 1 μM hairpin probe and 0.1 μM target DNA without (b) and with (c) KF exo-/dNTPs, and (d) 1 μM hairpin probe, 0.1 μM target DNA and 1 μM primer with KF exo-/dNTPs after incubation for 1 h at 37 °C. (B) DPV curves of designed biosensor responding to 100 pM target DNA without KF exo- (a), T7 RNA polymerase (b), and 0 (c) and 100 pM (d) target DNA with KF exo- and T7 RNA polymerase, respectively.
