“…The direct relationship is validated by the calibration curve in Figure b with the regression correlation coefficient ( R 2 ) of 0.991. The proposed sensor shows confirmations of remarkable electrocatalytic activity with the attainment of values as low as a detection limit of 0.5 nM and wide linear responses of 0.001–89 μM, and values are calculated using the standard formula − The evaluation of the analytical features of the LaV/h-BN-based electrochemical platform (Table ) signifies its efficient performance compared to those of previously reported studies, where, from the i – t curve, it is obtained to be 5 s on average for each and every addition of the analyte. The improved performance of the sensor can be recognized in accordance with the synergistic interactions between LaV and h-BN, the creation of electroactive edge sites, better electronic conductivity, and morphological encapsulation supporting electron transfer.…”

In the field of agriculture fungicides are vital, providing the most important ecosystem service for food production. The widespread use of these chemicals can significantly lead to various ecotoxicological threats with adverse effects, such as environmental changes, microbial resistance, and phytotoxicity. Electrochemical sensors offer enormous potential for the identification and monitoring of hazardous substances in accordance with their constructive characteristics, namely, precision, accuracy, sensitivity, and selectivity, over traditional analytical techniques. Here, we thus report the synthesis of the lanthanum vanadate/hexagonal boron nitride (LaV/h-BN) composite for the electrochemical determination of carbendazim (CZ), which is a widely used fungicide for disease management with critical risks associated with its overexposure. The combination of LaV and h-BN accelerates the formation of active sites, facilitating faster charge transfer and higher electronic conductivity. The synergistic effects greatly improve the preference of the modified electrode with increased sensitivity, a lower limit of detection, and wide linear responses toward CZ detection. The existence of variable oxidation states in the orthovanadate together with the unique properties of h-BN mark LaV/h-BN as an advanced material for specific applications in the family of rare-earth metal orthovanadate. Also, the deep eutectic solvent-assisted synthesis of the material creates an environmentally efficient system with reduced energy requisites to allow for applications in effective environmental monitoring.

“…The SPEs are affordable with the capability for mass production while maintaining sufficient reproducibility, with advantages of versatility and miniaturization [ 17 , 18 , 19 , 20 , 21 ]. The electrocatalytic activity of the bare electrode displays very substandard behavior [ 22 ]. Therefore, the electrode surface modification increases the sensitivity, reproducibility, and stability [ 23 , 24 , 25 , 26 , 27 ].…”

We used MoS2 nanosheets (MoS2 NSs) for surface modification of screen-printed electrode (MoS2NSs-SPE) aimed at detecting isoniazid (INZ) in the presence of acetaminophen (AC). According to analysis, an impressive catalytic performance was found for INZ and AC electro-oxidation, resulting in an appreciable peak resolution (~320 mV) for both analytes. Chronoamperometry, differential pulse voltammetry (DPV), linear sweep voltammogram (LSV), and cyclic voltammetry (CV) were employed to characterize the electrochemical behaviors of the modified electrode for the INZ detection. Under the optimal circumstances, there was a linear relationship between the peak current of oxidation and the various levels of INZ (0.035–390.0 µM), with a narrow limit of detection (10.0 nM). The applicability of the as-developed sensor was confirmed by determining the INZ and AC in tablets and urine specimens, with acceptable recoveries.

“…The CPZ shows its efficacy in treating vomiting, acute intermittent porphyria, nausea, anxiety, and chronic hiccups. Moreover, in the central nervous system (CNS), the CPZ has the ability to work with variety of receptors to generate strong spasmolytic, anticholinergic, adrenolytic, hypothermia, antiemetic, anesthetic, and antihistaminic effects [3,4].…”

A photochemical approach to anchor Au NPs on MXene as a prominent SERS substrate for ultrasensitive detection of chlorpromazine

As a novel two-dimensional (2D) material, metal carbide (MXene) has been identified as a hotspot research topic in the field of surface-enhanced Raman spectroscopy (SERS). Herein, we report the increment of SERS activity of titanium carbide (TiC) by incorporation of gold nanoparticles (Au NPs) by a facile photoreduction process for the detection of antipsychotic drug. TiC anchored with Au NPs produce a remarkable SERS enhancement by the synergistic action of chemical and electromagnetic mechanisms. The hotspots are formed in the nanometer-scale gaps between Au NPs on the TiC surface for the effective interaction with probe molecules. The proposed TiC/Au-NPs SERS substrate was employed for the detection of chlorpromazine (CPZ) with the wide linear range of 10 −1 -10 −10 M and the ultra-low limit of detection of 3.92 × 10 −11 M. Besides, the SERS effect of the optimized TiC/Au-NPs for the 532 nm excitation exhibits the enhancement factor in the order of 10 9 with the relative standard deviation of < 13% for the uniformity and < 8.80% for the reproducibility. To ensure the practical feasibility of the proposed TiC/Au-NPs SERS substrate, the spike and recovery method was used for the detection of CPZ in human biological fluids like urine and saliva. This work can open up a new approach to improve the SERS activity of MXene-based SERS substrate for practical applications, especially the determination of antipsychotic drugs in environmental pollution management.
