“…Because carbon has increased the density of the state near to Fermi level. In the meantime, binary metal oxides are highly stable and sensible . This makes the CaMoO 4 /P-CNT modified GCE act as an ideal electrode throughout this study and electrolyte contact material, finally showing high electrocatalytic rates in the detection of the target analyte.…”

The flavoring agent natural vanilla contains an abundant amount of the 4-hydroxy-3-methoxybenzaldehyde (Vanillin) biophenol compound. It is imperative to construct affordable and cost-effective approaches for determining the quantitative composition of Vanillin. In this work, we demonstrate a selective and sensitive electrochemical sensor for the detection of Vanillin by CaMoO 4 /P-CNT/GCE. We characterized our prepared nanomaterial using field emission scanning electron microscopy, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, Raman spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The electrochemical performance and analytical capabilities of this electrochemical sensor were evaluated using cyclic voltammetry, differential pulse voltammetry, and amperometry techniques. As a result of the nanocomposite, high conductivity, and high active surface area, the proposed electrochemical sensor has excellent sensitivity (DPV: 1.9718 and amperometry: 1.0947 μA μM −1 cm −2 ), low detection limit (DPV: 0.0017 and it amperometry: 0.00084 μM), high selectivity, and well reproducibility toward detection of Vanillin. In addition, real-sample analysis confirmed the high performance of the sensor developed in the present study.

Dimetridazole (DMZ), a nitroimidazole derivative, is a notable antibiotic that has garnered growing interest in the medical community owing to its noteworthy pharmacological and toxicological properties. Increasing interest is being directed toward developing high-performance sensors for continuous monitoring of DMZ in food samples. This research investigated an electrochemical sensor-based nano-sized ErVO4 attached to a sheet-like g-CN-coated glassy carbon electrode to determine dimetridazole (DMZ). The chemical structure and morphological characterization of synthesized ErVO4@g-CN were analyzed with XRD, FTIR, TEM, and EDS. Irregular shapes of ErVO4 nanoparticles are approximately 15 nm. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were followed to examine the electrochemical performance in pH 7 phosphate buffer solution for higher performance. This electrochemical sensor showed a low detection limit (LOD) of 1 nM over a wide linear range of 0.5 to 863.5 µM. Also, selectivity, stability, repeatability, and reproducibility studies were investigated. Furthermore, this electrochemical sensor was applied to real-time milk sample analysis for the detection of analytes.
