“…GA can be efficiently determined by electroanalytical methods since it is an electroactive compound undergoing irreversible oxidation. Moreover, thanks to the development of materials science, the modification of electrode surfaces with conductive or molecularly imprinted polymers (MIPs) or metal nanoparticles allows for the selective sensing of GA [ 12 ]. Different electrochemical sensors and methods have been proposed, mainly based on modifying classical macroelectrodes, such as glassy carbon, carbon paste, or gold with acrylic molecularly imprinted polymer films [ 13 , 14 , 15 ].…”

This paper presents a low-cost disposable sensor for gallic acid (GA) detection in non-alcoholic and alcoholic beverages using a screen-printed cell (SPC) whose working electrode (in graphite) is modified with electrosynthesized molecularly imprinted polypyrrole (eMIP). Our preliminary characterization of the electrochemical process shows that gallic acid (GA) undergoes irreversible oxidation at potentials of about +0.3 V. The peak potential is not affected by the presence of the eMIP film and alcohol percentages (ethanol) up to 20%. The GA determination is based on a differential pulse voltammetry (DPV) analysis leveraging its oxidation peak. The calibration data and the figures of merit of the analytical method (LOD, LOQ, and linear range) are calculated. To validate the feasibility of the sensor’s application for the dosing of GA in real matrices, some non-alcoholic and alcoholic beverages are analyzed. The results are then compared with those reported in the literature and with the total polyphenol content determined by the Folin–Ciocalteu method. In all cases, the concentrations of GA align with those previously found in the literature for the beverages examined. Notably, the values are consistently lower than the total polyphenol content, demonstrating the sensor’s selectivity in discriminating the target molecule from other polyphenols present.

In this study, Silver-Platinum (Pt-Ag) bimetallic nanoparticles were synthesized by the biogenic reduction method using plant extracts. This reduction method offers a highly innovative model for obtaining nanostructures using fewer chemicals. According to this method, a structure with an ideal size of 2.31 nm was obtained according to the Transmission Electron Microscopy (TEM) result. The Pt-Ag bimetallic nanoparticles were characterized using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffractometry (XRD), and Ultraviolet-Visible (UV-VIS) spectroscopy. For the electrochemical activity of the obtained nanoparticles in the dopamine sensor, electrochemical measurements were made with the Cyclic Voltammetry (CV) and Differential Pulse Voltammetry (DPV) methods. According to the results of the CV measurements taken, the limit of detection (LOD) was 0.03 µM and the limit of quantification (LOQ) was 0.11 µM. To investigate the antibacterial properties of the obtained Pt-Ag NPs, their antibacterial effects on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria were investigated. In this study, it was observed that Pt-Ag NPs, which were successfully synthesized by biogenic synthesis using plant extract, exhibited high electrocatalytic performance and good antibacterial properties in the determination of dopamine (DA).

Dopamine (DA) and ascorbic acid (AA) abnormal concentrations are intimately associated with many disorders, making the detection of these tiny molecules essential for keeping track of metabolic processes and preserving health. Due to its practicality from an economic standpoint, great sensitivity, and outstanding selectivity, electrochemical detection is a common technique for detecting tiny compounds. This technique's creation and use are equally crucial and cannot be disregarded. Due to their high surface-to-volume ratio and distinctive characteristics, nanomaterials are well-suited for various applications. In this study, we synthesized ZnCr 2 O 4 nanoparticles using an easy hydrothermal method. Given the difficulty of synthesizing nanoparticles and their importance in modern society, our research concentrated on this field. Based on statistical analysis, our results are consistent with the fabrication approach's anticipated results. This research aims to create electrochemical sensors that detect AA and DA in real time using ZnCr 2 O 4 nanocatalysts. The constructed sensor's oxidation potential is also significantly lower than that of recently published sensors of DA (E pa = 0.25 V) and AA (E pa = 0.45 V). In the concentration range of DA = 0.001−139 μM and AA = 0.01−126 μM, the suggested ZnCr 2 O 4 /GCE electrochemical sensing medium was used to detect AA and DA with great sensitivity. For AA and DA, the sensor demonstrated a detection limit of DA = 0.18 nM and AA = 12.56 nM. Furthermore, the ZnCr 2 O 4 /GCE sensor was an excellent tool for a technical feasibility study because the chosen possible interferences did not affect AA and DA sensing.
