The analytical performance of the detection system based on Y1-DNA and Y1-DNA/Y2-DNA-modified AuNPs. Sensitivity of DPV response for Y1-DNA (a) and Y1-DNA/Y2-DNA-modified AuNPs (b) incubated with different concentrations of T-DNA from 0.1 pM to 10 nM and the relationship between the peak currents and the concentrations of T-DNA (c), (d) the linear relationship between the peak currents and the concentration target.
