Fenitrothion is a widely prescribed pesticide in agriculture to control penetrating, chewing, and sucking pests on various crops. The electrochemical analytical technique is the obvious choice for establishing a fast, simple, cheap, and sensitive method for fenitrothion analysis. Nickel-iron spinel is an ideal material for electrode modification due to its good electrochemical catalytic properties, high specific surface properties of the nanoparticles, and target trapping ability of the metal hydroxyl sites. Therefore, this work intends to improve the detection of fenitrothion in the environmental matrix by adopting an electrochemical sensor. Herein, NiFe2O4 material was prepared in terms of the hydrothermal synthesis method. Its electrocatalytic performance in fenitrothion detection was evaluated. The synthesized NiFe2O4 was characterized using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS). The electrocatalytic performance of the electrode modified by NiFe2O4 was studied through cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). It was observed that the fabricated electrochemical sensor based on NiFe2O4 modified electrode exhibited higher electrocatalytic activity towards fenitrothion, resulting in a wide linear range of detection with a low limit of detection (LOD) of 1 × 10−8 mol l−1.

“…The residue was washed with water, ethanol, and methanol, collected, and dried at 60 °C to obtain 210 mg of CNT-CDN 3 (3). Triphenylphosphine (463 mg, 1.76 mmol) was added to a dispersion of CNT-CDN 3 (3) in DMF (195 mg, 9 mL), and the mixture was stirred at room temperature for 1 h. Afterward, the temperature was raised to 45 °C, 28% ammonia solution was added dropwise, and the reaction was allowed to stir at 45 °C for 24 h. The mixture was diluted with a water/EtOAc solution (1:1 v/v) and filtered under vacuum (0.1 μm Millipore membrane). The solid residue was washed with a chloroform/water/methanol solution (1:0.5:0.5) and finally with methanol.…”

“…Electrochemical sensors are considered useful analytical tools because of their sensitive and selective detection of analytes, rapid response, ease of operation, and low cost of reagents and instrumentation. Moreover, in the past decade, nanotechnology-based approaches have advanced significantly, leading to enhanced analytical response and miniaturization of devices. − In particular, modification of the electrode surface with carbon-based nanomaterials is a widely exploited strategy for the immobilization of recognition elements. The additional layer of nanomaterial that alters the shape and structure of the electrode surface can increase the electrical conductivity and surface area, improving sensitivity.…”

The study reports the use of nanoassembly based on cationic cyclodextrin carbon nanotubes (CNT-CDs) and ferrocenylcarnosine (FcCAR) for electrochemical sensing of Hg(II) in aqueous solution. β-cyclodextrins (CDs) were grafted onto CNTs by a click chemistry reaction between heptakis-(6-azido-6-deoxy)-β-cyclodextrin and alkyne-terminated CNTs. The cationic amine groups on the CD units were produced by the subsequent reduction of the residual nitrogen groups. The chemical composition and morphology of CNT-CDs were analyzed by X-ray photoelectron spectroscopy, scanning electron microscopy, and thermogravimetric analysis. A N,N-dimethylformamide dispersion of CNT-CDs was cast on the surface of screen-printed carbon electrodes (SPCEs), and the electrochemical response was evaluated by cyclic voltammetry (CV) using [Fe(CN) 6 ] 3− as the redox probe. The ability of SPCE/ CNT-CD to significantly enhance the electroactive properties of the redox probe was combined with a suitable recognition element (FcCAR) for Hg(II). The electrochemical response of the CNT-CD/FcCAR nanoassembly was evaluated by CV and electrochemical impedance spectroscopy. The analytical performance of the Hg(II) sensor was evaluated by differential pulsed voltammetry and chronoamperometry. The oxidative peak current showed a linear concentration dependence in the range of 1−100 nM, with a sensitivity of 0.12 μA/nM, a limit of detection of 0.50 nM, and a limit of quantification of 1 nM.

“…In contrast, electrochemical sensors promise improved sensitivity and compactness compared to competing portable technologies, as well as a reduction in sample analysis time and cost. [12][13][14] Chemically modified electrodes continue to be an emerging field of research, where diverse materials are being explored to ensure that electrochemical sensors are able to analyze numerous analytes. [15][16][17] For instance, a recent electroanalytical method developed by Hande and Yavuz 18 has demonstrated simple, accurate, selective, and rapid detection of IMQ using a boron-doped diamond (BDD) electrode in an anionic surfactant aqueous environment with a detection range of 0.021--4.2 μM and a LOD of 6.2 nM.…”

This study describes the development of a novel, ultrasensitive, and selective electrochemical sensor to determine imiquimod (IMQ) using a screen-printed carbon electrode (SPCE) modified with MXene (Ti3C2Tx), graphene nanoplatelets, and ionic liquid (Ti3C2Tx/GNPs/IL). This work reveals the synergistic effect of Ti3C2Tx, GNPs, and IL, where Ti3C2Tx and GNPs provide a large active electrode area and excellent electron transport, and IL exhibits remarkable electrocatalytic behavior. Benefiting from the excellent electrochemical properties of the composite, the developed sensing platform enabled superior electrochemical performance for IMQ in the broad linear range of 0.071–92.0 μM (R2 = 0.999) with a limit of detection (LOD) of 0.487 nM and a detection sensitivity of 7.558 μA μM−1 cm−2. Meanwhile, the sensor has shown good repeatability, reproducibility, stability, and anti-interference ability and has been subsequently used to detect IMQ in cream formulations with satisfactory recoveries (98.33%–99.34%) and lower relative standard deviations (<3%). The findings indicate that the newly developed sensor can contribute to the development of a portable, robust, and high-performance sensing strategy for multidisciplinary targets.
