Fig. 5From: Nonenzymatic coated screen-printed electrode for electrochemical determination of acetylcholineDPVs of MCSNP/SPE in 0.1 M PBS (pH 7.0) containing different concentrations of ACh (0.1, 2.5, 8.0, 20.0, 60.0, 100.0, 300.0 and 500.0 μM). Inset: The plot of the peak current as a function of ACh concentration in the range of 0.1–500.0 μMBack to article page
