Rapid monitoring of fungicide fenhexamid residues in selected berries and wine grapes by square-wave voltammetry at carbon-based electrodes

Facile Green Synthesis of NiO/NiCo2O4 Nanocomposite as an Efficient Electrochemical Platform for Determination of Dopamine

“…Furthermore, as displayed in Figure 3B. a linear relationship between the pH and the peak potential (E p ) was achieved with equation of y = À 0.0627pH + 0.6128 (R 2 = 0.922).The obtained slope value (62 mV/pH) is near to the theoretical value of 59 mV/pH which suggests that the number of protons and electrons participated in the process of DA oxidation is the same [36]. As shown in Figure 3C, the peak current at pH7.0 was highest, therefore, 0.1 M phosphate buffer solution with pH = 7.0 applied for more investigations in this study.…”

Carbon-Based Materials and Their Applications in Sensing by Electrochemical Voltammetry

“…Nevertheless, plasma seems to be a very useful method for element-doping, since it is fast, safe to use and environmentally friendly. Brycht et al studied the difference in fenhexamid sensitivity of basic carbon electrodes such as glassy carbon electrodes, glassy carbon paste, conventional carbon paste electrodes and carbon paste electrodes modified with MWCNTs (Figure 13d) [127]. When comparing basic electrodes, the conventional carbon electrode has advantages in both the linear range and limit of detection.…”

A new electrochemical DNA biosensor for determination of anti-cancer drug chlorambucil based on a polypyrrole/flower-like platinum/NiCo2O4/pencil graphite electrode

“…[5][6][7] Instead, individual analysis of these drugs can be performed in simple processes using electrochemical methods because of some unique properties such as rapid analysis, costeffectiveness, portability and simplicity. [8][9][10][11][12][13][14][15][16] Carbon paste, pencil graphite electrode, glassy carbon, screen-printed, etc. are the most regular electrodes for the electrochemical sensing of different analytes.…”
