Sensitivity increase and LOD of the PEDOT/GO coated CFE. Average (±SEM) percent increase in sensitivity for DA was determined for each deposition duration by comparing post coating sensitivities to the corresponding bare electrode sensitivities (average raw sensitivities displayed in Figure 4c). PEDOT/GO significantly decreases the LOD for DA when the deposition duration exceeds 10 s (* two-way repeated measures ANOVA, PEDOT/GO: F(1,27)=45.0, p<5E⁻⁷).
