“…Reversible electrochemical behavior were observed for the redox probes on the PGE and 8-NQ/PGE electrodes. To determine the coating cycle, different coating numbers (10,15,20,25,30,35) were used. It was observed that the peaks of the redox probes increased clearly up to 15 CV and decreased after this number of coatings.…”

In this study, we developed a facile and low-cost method to prepare a modified electrode named 8-NQ/PGE by coating the pencil graphite electrode (PGE) surface with 8-nitroquinoline (8-NQ) molecule. The surface modification process was carried out by electrochemical reduction of 8-NQ on the PGE surface in ethanol solution. The characteristic of the prepared electrode was analyzed through cyclic voltammetry (CV) with redox probes, differential pulse voltammetry (DPV), electrochemical impedance spectroscopy (EIS), Fourier transformed infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The method was developed to determine rutin (Ru) with the modified electrode (8-NQ/PGE). The developed electrode showed excellent performance for Ru oxidation in a pH 3.0 Britton Robinson buffer (BR). In this media, linearly increasing anodic peak currents were observed with the concentration of Ru in two wide concentration ranges (i.e., 0.016–0.96 µM and 0.96‒19.73 µM), therein the sensor showed a low detection limit (i.e., 4.14 nM) (3s/m). It displayed good stability and selectivity. Also, it was used successfully for the determination of Ru in orange juice samples.

In the present work, a green method improved by surface response methodology (SRM) has been used for the synthesis of zinc oxide nanoparticles (ZnONPs) from coffee husks extract, in which Santa Barbara‐15 (SBA‐15) mesoporous silica has been embedded. The composite formed has been drop coated on bare glassy carbon electrode and the resulting sensor (ZnONPs/SBA‐15/GCE) was used for the sensing of acetaminophen (ACT). Reaction factors such as pH, incubation time and precursor concentration were optimized during nanoparticles synthesis using SRM. The synthesized nanoparticles and the composite were characterized by ultraviolet‐visible spectrophotometry (UV‐Vis), Fourier transform infrared (FTIR) spectroscopy, powder X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray (EDX/EDX‐mapping) analysis, thermogravimetry analysis/differential thermogravimetry (TGA/DTG), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS), showing the good elaboration of ZnONPs/SBA‐15/GCE. After optimization of parameters susceptible to affect the detection limit of ACT, the calibration curve was plotted from 4 μM to 32 μM, showing good linear response with a detection limit of 0.11 μM. The developed sensor shows good sensitivity, reproducibility, repeatability and storage stability at room temperature and was successfully applied for the determination of ACT in pharmaceutical sample.

“…Therefore, it is of great significance to establish a fast and portable method for detecting the content of rutin. Different techniques have been reported for the determination of rutin such as high-performance liquid chromatography (HPLC) [ 3 , 4 ], chemiluminescence [ 5 ], capillary electrophoresis [ 6 ], and the electrochemical method [ 7 , 8 , 9 , 10 , 11 ]. Among them, electrochemical methods have generated great research interest over the past decade due to the merits of the fast response, high sensitivity, and minimal sample requirements.…”

To build a portable and sensitive method for monitoring the concentration of the flavonoid rutin, a new electrochemical sensing procedure was established. By using nitrogen-doped carbonized polymer dots (N-CPDs) anchoring few-layer black phosphorene (N-CPDs@FLBP) 0D-2D heterostructure and gold nanoparticles (AuNPs) as the modifiers, a carbon ionic liquid electrode and a screen-printed electrode (SPE) were used as the substrate electrodes to construct a conventional electrochemical sensor and a portable wireless intelligent electrochemical sensor, respectively. The electrochemical behavior of rutin on the fabricated electrochemical sensors was explored in detail, with the analytical performances investigated. Due to the electroactive groups of rutin, and the specific π-π stacking and cation–π interaction between the nanocomposite with rutin, the electrochemical responses of rutin were greatly enhanced on the AuNPs/N-CPDs@FLBP-modified electrodes. Under the optimal conditions, ultra-sensitive detection of rutin could be realized on AuNPs/N-CPDs@FLBP/SPE with the detection range of 1.0 nmol L−1 to 220.0 μmol L−1 and the detection limit of 0.33 nmol L−1 (S/N = 3). Finally, two kinds of sensors were applied to test the real samples with satisfactory results.
