“…However, GCE has a small surface area, providing sluggish electron transfer [21]. Per reports, carbon film electrodes demand a very high temperature for preparation through pyrolysis [22,23]. On the other hand, the CPE drew the most attention as a working electrode in electrochemical analysis, providing high mechanical stability, increased sensitivity, selectivity, and stability [24,25].…”

The present study involves detecting and determining CIP by a new electrochemical sensor based on graphene (Gr) in the presence of sodium dodecyl sulfate (SDS) employing voltammetric techniques. Surface morphology studies of the sensing material were analyzed using a scanning electron microscope (SEM) and atomic force microscope (AFM). In the electroanalysis of CIP at the developed electrode, an enhanced anodic peak response was recorded, suggesting the electro-oxidation of CIP at the electrode surface. Furthermore, we evaluated the impact of the electrolytic solution, scan rate, accumulation time, and concentration variation on the electrochemical behavior of CIP. The possible electrode mechanism was proposed based on the acquired experimental information. A concentration variation study was performed using differential pulse voltammetry (DPV) in the lower concentration range, and the fabricated electrode achieved a detection limit of 2.9 × 10−8 M. The proposed sensor detected CIP in pharmaceutical and biological samples. The findings displayed good recovery, with 93.8% for tablet analysis and 93.3% to 98.7% for urine analysis. The stability of a developed electrode was tested by inter- and intraday analysis.

We report on the analytical performance of boron-doped diamond thin-film electrodes for the detection of the virulence factor, pyocyanin (PYO). The results reported herein confirm the utility of diamond electrodes for the sensitive and reproducible detection of pyocyanin in a 0.1 mol L À 1 phosphate buffer (pH 7.4) when using amperometric detection coupled with flow injection analysis (FIA) or square wave voltammetry (SWV). Pyocyanin was reductively detected by hydrodynamic voltammetry in FIA at an E 1/2 of À 0.31 V vs. Ag/AgCl (3 mol L À 1 KCl). The detection figures of merit were a linear dynamic range from 100 to 0.08 μmol L À 1 , a response reproducibility of 1.3 % (RSD), and a limit of detection of 0.09 μmol L À 1 (S/N = 3). A comparable linear dynamic range, response reproducibility and limit of detection were observed in preliminary square wave voltammetry measurements. Importantly, these detection figures of merit were obtained using boron-doped diamond electrodes that received no conventional pretreatment. Some comparison data are presented for nitrogenincorporated tetrahedral amorphous carbon (ta-C : N) and glassy carbon (GC) electrodes.
