The electrochemical impedance spectroscopic approach, which is largely based on similar methods used to analyze circuits in electrical engineering practice, was developed by Sluyters and coworkers (4) and later extended by others (8-12). It deals with the variation of total impedance in the complex plane [as represented in Nyquist plots (Section...

Mousavi et al. have used PEDOT-CNT composite as ion-to-electron transducer in the fabrication of potassium ISEs [19]. In this work, PEDOT was electrochemically S5mthesized using negatively charged multi-walled CNTs (MWCNTs) as counterions. Results from cyclic voltammetric (CV) and electrochemical impedance spectroscopic (EIS) measurements shown in Fig. 11.1, reveal that the PEDOT-MWCNT film exhibits higher redox capacitance than a film based on PEDOT doped with chloride [Cr) ions, i.e., PEDOT-Cl. This sufficiently high redox capacitance is one of the conditions necessary for stable potential in all-solid-state ISEs having an ECP as the solid contact [23].

In order to evaluate the behavior of the detection platform and compare the two alternative detection configurations, electrochemical impedance spectroscopic monitoring of HeLa cells has been performed. Fig. 3 shows examples of Cl values acquired using the ECIS vertical configuration. As expected, a peak frequency, indicating the most sensitive region of the...
