“…In another study, a limit of detection of 0.0036 was achieved using a threedimensional cubic europium/cuprous oxide-modified glassy carbon electrode (Eu 3 + /Cu 2 O/GCE). [103] NVP has been successfully detected using various electrode materials, but as of current, not on a NiSe 2 QD modified gold electrode. Additionally, there is a limited applicability for these sensors in real wastewater samples that has to be investigated.…”

An electrochemical sensor‐based on nickel selenide quantum dot, capped with 3‐mercaptopropionic acid (3‐MPA), was embedded on an L‐cysteine modified gold electrode for nevirapine (NVP) detection. The 3‐MPA‐NiSe2QD material was fully characterised using FTIR, SEM, Raman, HR‐TEM, XRD, SAXS, PL and UV‐Vis. Differential pulse voltammetry was used to study the electrochemical responses of 3‐MPA‐NiSe2QD/L‐cyst/Au electrochemical sensor to NVP, with a characteristic oxidation peak at 0.76 V. The electrochemical sensor obtained a low limit of detection (LOD) value of 0.0133 pM (0.0035 ng/L), limit of quantification (LOQ) of 0.0442 pM (0.0118 ng/L) and sensitivity of 6.15 μA/pM with a linear range of 0.25–0.63 pM, respectively. Thus, the reproducibility, stability, and repetitive usability shown by the proposed sensor made it suitable for the determination of nevirapine in real wastewater samples.

“…40,43 GCE/Eu 3+ /Cu 2 O CLFNs.-An interesting strategy to detect NVP has been proposed by Foroughi and co-workers using DPV on a three-dimensional cubic of europium (Eu) 3+ /cuprous oxide (Cu 2 O) with clover-like face-centred nanostructures. 34 Other various approaches of electrochemical characterization like CV and EIS were also employed. In this approach, a GCE was modified with Eu 3+/ Cu 2 O CLFN and then applied to distinguish NVP.…”

Since the 1980s, the HIV/AIDS pandemic has been a global concern and remains despite the tremendous efforts and successes in the development of antiviral drugs. The drug development and formulation process are not without challenges. However, the effective use of excipients can allow formulators to circumvent or at least minimize the impact of these challenges. Some of the challenges include ensuring a high quality of actives, free from impurities, and ensuring administration in appropriate quantities. Incorrect dosing can have a detrimental impact on the body. Evaluation of the quality and physiological function of these drugs in pharmaceutical and biological samples is vital. We explore the application of electrochemical methods for the detection of these drugs. Electrochemical methods are versatile and cheaper in comparison to conventional techniques. This review paper provides the latest developments and new trends in electroanalysis of the first generation of nonnucleoside reverse transcriptase inhibitors drugs. Furthermore, we highlight several phenomena occurring on bare solid electrodes and modified electrodes, including underlying mechanisms. Recent data shows that modified electrodes based on nanoparticles present substantial advantages over their non-modified counterparts enabling portability, higher selectivity, and multiple detection capabilities. These characteristics make nanoparticles promising candidates for the design of sensors.

“…Among these, voltammetry is the proposed method for bypassing such problems due to its unique advantages such as rapid response, inherent selectivity, great sensitivity, simplicity, cost-effectiveness, and relatively short analysis time to determine organic molecules such as drugs and relevant molecules in biological fluids and pharmaceutical doses (Maaref et al, 2018;József et al, 2019;Salajegheh et al, 2019; Sargazi et al, 2019;Shetti et al, 2019;Kulkarni et al, 2020;Malode et al, 2020;Vakili Fathabadi et al, 2020;Liu et al, 2021a;Foroughi et al, 2021;Obireddy and Lai, 2021;Obireddy and Lai, 2022). An effective strategy to increase the electrochemical performance of sensors is to design composites by integrating highly electrocatalytic active materials with excellent conductivity materials, resulting in the electrode surface modification (Zhang et al, 2016;Foroughi and Ranjbar, 2017;Shetti et al, 2018;Fathi et al, 2020;Azizabadi et al, 2021;Liu et al, 2021b;Liang et al, 2022;Qi et al, 2022).…”

This study synthesized a La2O3@snowflake-like Cu2S composite to fabricate an electrochemical sensor for sensitively simultaneous detection of diclofenac and chlorzoxazone exploiting an easy hydrothermal approach, followed by analysis with XRD, FE-SEM, and EDX methods. According to voltammetric studies, the electrocatalytic diclofenac and chlorzoxazone oxidations on the electrode modified with La2O3@SF-L Cu2S composites were increased, with greater oxidation currents, as well as the oxidation potential was significantly decreased due to synergetic impact of La2O3@SF-L Cu2S composites when compared with the pure SF-L Cu2S NS-modified electrode. The differential pulse voltammetry findings showed wide straight lines (0.01–900.0 μM) for La2O3 NP@SF-L Cu2S NS-modified electrode with a limit of detection (LOD) of 1.7 and 2.3 nM for the detection of diclofenac and chlorzoxazone, respectively. In addition, the limit of quantification was calculated to be 5.7 and 7.6 nM for diclofenac and chlorzoxazone, respectively. The diffusion coefficient was calculated to be 1.16 × 10−5and 8.4 × 10−6 cm2/s for diclofenac and chlorzoxazone oxidation on the modified electrode, respectively. Our proposed electrode was examined for applicability by detecting diclofenac and chlorzoxazone in real specimens.
