“…Juices, wines, and tea infusions are routinely diluted with distilled water or buffer before use. − There are varied dilutions that have been performed; for instance, for wines, dilutions as high as 1:100 to as low as 1:5 are stated in the literature. On the other hand, many researchers have reported the use of neat samples of beverages such as wines, tea, and fruit juices without any pretreatment step. , The excellent agreement between the values obtained from biosensors and HPLC analysis suggests that the effect of the sample matrix is insignificant during the proposed biosensing analysis. In contrast, for solid samples, the quantitative analysis of antioxidants is normally achieved by preparing and analyzing sample extracts.…”

“…4 Rutin, gallic acid, and chlorogenic acid are some examples of phenolic dietary antioxidants that are widespread in various food items. 5,6 Conventional methods of estimating phenolic content in food and beverage samples include the Folin−Ciocalteau (F− C) assay, high-performance liquid chromatography (HPLC), spectrophotometric analysis, capillary electrophoresis, and electroanalytical methods. The F−C assay spectroscopically determines the transfer of electrons from phenolic compounds to phosphotungstic/phosphomolybdic acid complexes.…”

Antioxidants are known to exhibit a protective effect against reactive oxygen species (ROS)-related oxidative damage. As a result, inclusion of exogenous antioxidants in the diet has greatly increased. In this sense, detection and quantification of such antioxidants in various food and beverage items are of eminent importance. Monophenols and polyphenols are among the most prominent natural antioxidants. In this regard, biosensors have emerged as a simple, fast, and economical method for determination of such antioxidants. Owing to the fact that majority of the phenolic antioxidants are electroactive, oxidoreductase enzymes are the most extensively availed bioreceptors for their detection. Herein, the different types of oxidoreductases that have been utilized in biosensors for the biorecognition and quantification of natural phenolic compounds commonly present in foods and beverages are discussed. Apart from the most accustomed electrochemical biosensors, this review sheds light on the alternative transduction systems for the detection of phenolic antioxidants. Recent advances in the strategies involved in enzyme immobilization and surface modification of the biosensing platform are analyzed. This review aims to provide a brief overview of the latest developments in biosensor technology for phenolic antioxidant analysis in foodstuffs and future directions in this field.

“…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.

The electrification of the production of fine chemicals has received increased interest in combating petrochemical routes with a high carbon footprint. Oxidising biomass from waste streams with concomitant hydrogen production, such as the transformation of lignin to vanillin, would be a great asset. Here, we show the combination of activity screening using a scanning droplet cell on a thin‐film Ni−Fe library and performance testing in a flow‐through cell with pulse electrolysis. The identified optimal Ni−Fe material composition was prepared on Ni foam with a polymer/metal precursor spray method. Full factorial and Doehlert matrix designs were employed to better comprehend each parameter‘s effects on the complex system. The best conditions for the electrooxidation of Kraft lignin at room temperature were at E1st=1.36 V vs RHE, t1st=1 s for the first pulse and E2nd=1.60 V vs RHE and t2nd=15 s for the second pulse, leading to the significantly improved production of 2.15 μmols of vanillin at room temperature. Pulsed chronopotentiometry was demonstrated to be a cost‐effective and robust technique with a simple setup for the valorisation of Kraft lignin. Combined with a subsequent thermolysis step, 8.05 μmols of vanillin were obtained.
