Electrochemical Detection of Sequence-Specific DNA with the Amplification of Gold Nanoparticles
Figure 6
DPV response of the intercalated adriamycin recorded for the probe DNA modified electrode that hybridized with various concentrations of complementary DNA: (a) 0 M; (b) 5.0 × 10−13 M; (c) 1.0 × 10−12 M; (d) 5.0 × 10−12 M; (e) 1.0 × 10−11 M; (f) 1.0 × 10−10 M; (g) 1.0 × 10−9 M. Inset: Peak current () of the intercalated adriamycin versus logarithm of concentration of complementary DNA. Error bars show the standard deviations of measurements taken from three independent experiments. Accumulation time of adriamycin: 20 min; hybridization time: 25 min. The DPV parameters were the same as in Figure 2(B).
