Analytical performances at the oPPy modified dual electrode biosensor 1.

Analyte Biosensor Sensitivity (µA/mM) Linear Range (µM) LOD 2 (µM/pmol)
PCh Pt/oPPy/ChO-ALP 0.197 3–1000 2.7/53.6
Ch Pt/oPPy/ChO-ALP 1.30 0.3–1000 0.19/3.9
Ch Pt/oPPy/ChO 1.39 0.3–1000 0.28/5.6

1 Carrier solution: borate buffer (pH 9, I 0.1 M); flow rate 1 mL/min; injection volume 20 µL. Other experimental conditions as described in Section 2. 2 LOD: relative (µM) and absolute (pmol injected) limit of detection calculated at a signal-to-noise ratio of 3.
