“…The main reason is that the fouling and regeneration of electrode surface [ 2 ]. In recent years, new electrochemical sensing methods using chemically modified electrodes (CMEs) for vanillin detection have been investigated [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. For example, Shang et al developed a vanillin electrochemical sensor based on AuPd-graphene hybrid.…”

In this paper, CeO2 nanoparticles were synthesized by the solvothermal method and dispersed uniformly in graphene oxide (GO) aqueous solution by ultrasonication. The homogeneous CeO2-GO dispersion was coated on the surface of a glassy carbon electrode (GCE), and the CeO2/electrochemically reduced graphene oxide modified electrode (CeO2/ERGO/GCE) was obtained by potentiostatic reduction. The results of X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) showed that CeO2 nanocrystals were uniformly coated by gossamer like ERGO nanosheets. The electrochemical behavior of vanillin on the CeO2/ERGO/GCE was studied by cyclic voltammetry (CV). It was found that the CeO2/ERGO/GCE has high electrocatalytic activity and good electrochemical performance for vanillin oxidation. Using the second derivative linear sweep voltammetry (SDLSV), the CeO2/ERGO/GCE provides a wide range of 0.04–20 µM and 20 µM–100 µM for vanillin detection, and the detection limit is estimated to be 0.01 µM after 120 s accumulation. This method has been successfully applied to the vanillin detection in some commercial foods.

“…Table 1 [27–33] gives the comparison of VA sensors with proposed sensor. PTOMCNPE provides lower LOD as compared to gold electrode/ 3‐amino‐1,2,4‐triazole‐5‐ thiol, [28] Cajeput tree bark derived activated carbon/GCE, [29] arginine/graphene/GCE, [30] screen‐printed electrode/CNT, [31] and graphene paste/CTAB, [32] PNMCNTPE [34] and near LOD to T3T−Au/GE [33] . The developed sensor is relatively simple and low cost with high sensitivity.…”

In this work, the active poly (titan yellow) and octoxynol‐9 modified carbon nanotube paste electrode (PTOMCNPE) was prepared and characterized through a Field emission scanning electron microscope (FE‐SEM), Energy‐dispersive X‐ray spectroscopy (EDX), and Electrochemical impedance spectroscopy (EIS). PTOMCNPEpromotes the detection and quantification of vanillin (VA). The electrochemical parameters such as the number of electropolymerization cycles, effect of surfactant,pH, and scan rate were optimized to get an enhanced current signal for the targetmolecule. Under calibrated conditions, the concentration linearity for vanillin was obtained from 2.0‐40.0 μM using both cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The limitof detection(LOD) for VA was found to be 4.9×10−8 M and 9.31×10−8 M using DPV and CV, respectively. The stable and selective VA sensor was applied to food analysis with excellent recovery.

“…Carbon-based electrodes are currently in widespread use in electroanalytical chemistry for many different applications. This is due to their large potential window, low cost, rich surface chemistry, low background current, chemical inertness, and congruity [29][30][31][32][33][34][35]. Carbon is a distinctive and necessary element in our world.…”

This review summarizes some recent developments in the fabrication of modified sensors and biosensors using carbon-based materials. The great potential of carbon-based electrodes as sensing platforms is exciting due to their unique electrical and chemical properties, high accessibility and high biocompatibility. Carbon-based materials are particularly interesting due to almost infinite possibility of their functionalization with a wide variety of organic molecules, biologically important compounds and pharmaceuticals. This review is specifically focused on recent developments in the utilization of various carbon-based electrodes in sensing devices for the electrochemical investigation of drug molecules. Various voltammetric techniques considered in this effort include linear sweep voltammetry (LSV), cyclic voltammetry (CV), differential pulse voltammetry (DPV), square wave voltammetry (SWV), and square wave adsorptive stripping voltammetry (SWAdSV). The carbon-based electrode materials considered in this review comprise carbon paste, carbon nanotubes, graphite, graphene, and glassy carbon. The analytes chosen are some routinely used drugs such as paracetamol (PC), diclofenac sodium (DCF), 5-fluorouracil (5-FU), cetirizine (CTZ) and salbutamol (SAL). All here reported sensing electrodes produced very good results in electrochemical investigations of these drug molecules.
