Figure 6

(a) Nyquist plot of bare (black color), QDs (red color) and MAA-QDs (blue color) modified GCE. (b) Nyquist plot of MAA-QDs (black color) after conjugation with different dilutions of COx: 1:1 (red color), 1:10 (blue color), 1:100 (green color), and 1:1000 dilution (pink color) COx conjugated QDs. The insets show the high frequency part of the plot.
