Plotted data corresponds to an 8 point moving average of amperometric evaluation of flowing (100 μL min−1) K3[Fe(CN) 6] using bare Kanichi electrode array at 0.4 V (vs. Ag/AgCl) pseudo-reference in PBS buffer (pH 7.4). Peaks indicate concentrations of K3[Fe(CN) 6] (2.5, 5, 10, 15 mM) sequentially in triplicate. Inset indicates plotted concentration vs relative peak area response where circles indicate mean peak area values from the evaluations carried out, and error bars indicate the standard deviation (n = 4), y = 1.26162x − 1.9174 R2 = 0.98.
