In this work, the nanosheet‐assembled lindgrenite microflowers (chemical formula: Cu3Mo2O9) were synthesised through a simple process and low‐cost raw materials at room temperature in aqueous solution without using any surface‐active agent. The tightly interlaced nanosheets, like petals, can increase the specific surface area, which can bring about higher electrocatalytic activity and electroanalysis sensitivity. Thus, lindgrenite microflowers were prepared as an electrochemical sensor and successfully applied in the detection of paracetamol through the modified glass carbon electrode. Furthermore, this electrochemical reaction process was simulated at the ab‐initio level to reveal the catalytic mechanism, and the simulation results agreed well with electrochemical experiments. The electrochemical performance of the lindgrenite microflowers modified glassy carbon electrode (GCE) was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The linearity of paracetamol ranged from 0.05 to 1200 μM (IT method) and 0.05 to 1000 μM (DPV method), low detection limit (0.01 μM) and high sensitivity (5.11 mA mM−1 cm−2) towards paracetamol. Moreover, this sensor was applied to detect paracetamol in human blood serum samples. The excellent results demonstrated that the prepared electrode not only showed a desirable linear range towards paracetamol but also exhibited practical applicability and reliability towards human serum samples detection.

“…These electrodes have a sensitive layer, acting as the essential part of a transducer system, that transforms the chemical reaction into an electrical signal, detectable and interpretable using voltammetric techniques. Recently, CPEs have integrated diverse particulate materials and primary synthetic nanoparticles with varied compositions [13][14][15][16][17][18], where different metal oxides [12,[19][20][21][22][23][24][25][26][27][28], nanocomposites [29], zeolites [30,31], dyes [32] and clay minerals [33] have attracted significant attention to preparing CPE-based chemically modified electrodes [34][35][36][37][38]. On the other hand, clays are minerals dominantly made from a colloid system containing soils, sediments, rocks, and water [39,40].…”

Paracetamol (PCT), or acetaminophen, is an important drug used worldwide for various clinical purposes. However, the excessive or indiscriminate use of PCT can provoke liver and kidney dysfunction; hence, it is essential to determine the amount of this target in biological samples. In this work, we develop a quick, simple, and sensitive voltammetric method using chemically modified electrodes to determine PCT in complex matrices, including human serum and commercial solid formulations. We modify the carbon paste electrode with stevensite monoclinic clay mineral (Stv-CPE), using cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy to characterise and detect PCT. The kinetics study provides a better electrochemical characterisation of the electrode behaviour, finding the detection and quantitation limits of 0.2 μM and 0.5 μM under favourable conditions. Further, the best linear working concentration range is 0.6–100 μM for PCT, applying the proposed method to the quantitative determination of PCT content in reference tablet formulations and biological samples for validation.

“…Due to the low degradability and high toxicity, HQ is considered as a serious environmental pollutant. [8][9][10][11] Presently, some electrochemical methods have been developed to detect the content of PCM and HQ in environmental water, [12][13][14] since the electrochemical method have many advantages such as rapid analysis, low cost, high selectivity and sensitivity. 15,16 For instance, Murugan et al 4 fabricate SnS/TiO2@GO composite modified electrode for the electrochemical determination of PCM; Li et al 17 used octadecylamine-functionalized graphene vesicles for voltammetric sensing of HQ.…”

By using dopamine (DA) as a functionalized and linked agent, a novel nanohybrid nitrogen-doped carbon black/reduced graphene oxide (NCB/rGO) was prepared successfully via a green three-step process in this work, and then, NCB/rGO was applied in the field of electrochemical sensing through introducing the case of simultaneous determination of two pollutants, hydroquinone (HQ) and paracetamol (PCM). The produced NCB/rGO was characterized by various technologies including transmission electron microscopy, X-ray diffraction, Raman spectroscopy and electrochemical method. Owing to the synergetic advantages from each component in nanohybrids, the results showed that the NCB/rGO nanohybrids can exhibit excellent electrochemical sensing performances and the responsive peak current of HQ and PCM at NCB/rGO electrode are ∼3.2 and 23.0 times as high as those at single CB and rGO electrode, respectively. After optimizing the detection conditions, the analytical responses of NCB/rGO modified electrode has a linear range between 0.05 and 20.0 μM for both targets with low detection limit (16.5 nM for HQ and 26.2 nM for PCM). It’s believed that the developed NCB/rGO novel nanohybrids will have important applications in electrochemical sensing of HQ and PCM as well as many other analytes.
