The DPV response of DNR (1.0 × 10−5M) as indicator in PBS (0.1 M, pH 7.4) recorded for the AuNPs/CA/nBDD electrode with probe DNA without hybridization (f), hybridized with non-complementary sequence (e), three-base mismatch sequence (d), two-base mismatch sequence (c), one-base mismatch sequence (b), and complementary sequence (a). Different target DNA concentration: 1.58 × 10−7 M; DPV parameters: Amplitude: 0.05 V; pulse period: 0.2 s; pulse width: 0.05 s.
