Electrode properties (choline calibration data)

Enzyme	Sensitivity (pA/μM)	LOD (nM)	R²	Choline:AA
AChE+ChOx	9.60 ± 1.55	236.75 ± 46.48	0.992 ± 0.004	289.32 ± 94.40
ChOx	8.19 ± 1.02	231.91 ± 17.69	0.993 ± 0.002	366.14 ± 81.79

Data are based on 15 Pt- recording sites per enzyme coating type [Mean ± S.E.M]; LOD, limit of detection; R², linearity of the response of the microelectrode to increasing concentrations of choline; AA, ascorbic acid
