Performance of the sensor system in blood matrix diluted 6x with 0.5 M HCl. (a) Reproducibility at 0.3 μg dL−1 Pb in blood matrix (n = 3 repetitions for each sensor). (b) Reproducibility at 3 μg dL−1 Pb (n = 3 repetitions for each sensor). In both panels, stripping peak area is plotted on the primary (left) axis, while the variability of each sensor is plotted on the secondary (right) axis.
