“…In the proposed daily dose (50–150 mg), DF is completely tolerated [ 84 ]. Although no problems are caused when an appropriate amount of DF is used, its excessive or continuous use may cause symptoms such as epigastric discomfort, gastric ulcer, hematuria; meantime, the accumulated mass of toxic substances can cause kidney and liver dysfunctions [ 85 ]. Furthermore, the ubiquity of DF in the environment impairs fish health and water quality due to its poor degradation [ 86 ].…”

The dynamic production and usage of pharmaceuticals, mainly painkillers, indicates the growing problem of environmental contamination. Therefore, the monitoring of pharmaceutical concentrations in environmental samples, mostly aquatic, is necessary. This article focuses on applying screen-printed voltammetric sensors for the voltammetric determination of painkillers residues, including non-steroidal anti-inflammatory drugs, paracetamol, and tramadol in environmental water samples. The main advantages of these electrodes are simplicity, reliability, portability, small instrumental setups comprising the three electrodes, and modest cost. Moreover, the electroconductivity, catalytic activity, and surface area can be easily improved by modifying the electrode surface with carbon nanomaterials, polymer films, or electrochemical activation.

“…Electrochemical analysis is practically free of organic solvents, is fast, and can be used on a large scale, thanks to portable, miniaturised tools [ 6 , 8 , 9 ]. Electrochemical methods, including voltammetry, use electrodes as a conversion element, the surface of which interacts with the analyte and converts the information obtained into a signal that can be measured and identified by means of electrochemical analysis control devices [ 10 ]. The most frequently used method in quantitative analysis is voltammetry coupled with pulse waveform and the accumulation of analyte on the electrode surface, e.g., square-wave adsorptive stripping voltammetry (SWAdSV).…”

In this paper, we propose the first analytical procedure—using a screen-printed carbon electrode modified with carbon nanofibers (SPCE/CNFs)—for the detection and quantitative determination of an electroactive disubstituted fused triazinone, namely 4-Cl-PIMT, which is a promising anticancer drug candidate. The electrochemical performances of the sensor were investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and square-wave adsorptive stripping voltammetry (SWAdSV). The presence of carbon nanofibers on the sensor surface caused a decrease in charge-transfer resistance and an increase in the active surface compared to the bare SPCE. Under the optimised experimental conditions, the proposed voltammetric procedure possesses a good linear response for the determination of 4-Cl-PIMT in the two linear ranges of 0.5–10 nM and 10–100 nM. The low limits of detection and quantification were calculated at 0.099 and 0.33 nM, respectively. In addition, the sensor displays high reproducibility and repeatability, as well as good selectivity. The selectivity was improved through the use of a flow system and a short accumulation time. The SWAdSV procedure with SPCE/CNFs was applied to determine 4-Cl-PIMT in human serum samples. The SWAdSV results were compared to those obtained by the ultra-high-performance liquid chromatography coupled with electrospray ionization/single-quadrupole mass spectrometry (UHPLC-ESI-MS) method.

“…When dopamine levels are diminished in the human body, it causes Parkinson and schizophrenic diseases [1]. Furthermore, dopamine regulates all brain functions; it may protect the human heart racing and widen blood vessels in the viscera, which is effective in the treatment of cardiogenic shock and kidney failure [2]. Therefore, measurement of dopamine level in the human body is necessary.…”

“…Moreover, immunoassays, biosensors, and other disciplines of research use the electrochemical sensors for various applications. Nowadays, metal oxide based on electrochemical sensors received huge attention towards dopamine detection [2]. Among the metal oxide, CuO semiconductors are excellent candidates for dopamine detection.…”

At present, the determination of dopamine (DA) is enormously necessary for the human body. Since then, it has played a crucial role in the brain that affects mood, sleep, memory, learning, and concentration. Dopamine insufficiency is a threat to human health. Dopamine recognition is important to avoid this problem. Copper oxide (CuO) nanoparticles are one of the potentials which can be used in the detection of dopamine level in the sample. In this work, CuO was synthesized by a simple chemical precipitation technique and modified by polyvinyl alcohol (PVA) as a capping agent. The nanomaterials manufactured are used for the detection of dopamine in 0.1 M PBS medium at room temperature. The CuO/PVA-modified electrode shows better electrocatalytic activity than CuO/GCE (glassy carbon electrode). The constructed dopamine biosensor of copper oxide-PVA nanocomposites also has extraordinary selectivity, stability, sensitivity (183.12 μA mM-1 cm-2), and a minimum level detection limit of 0.017 μM, is inexpensive, and has minimal effort and rapid detection of dopamine.
