“…Numerous optical and electrochemical analytical methods for Arg determination have been developed to date [ 2 , 12 – 15 ]. Simple and quick optical methods are based on the well-known Sakaguchi reaction, which involves the formation of color product between Arg and 8-hydroxyquinoline [ 12 , 16 ].…”

“…ADI and ArgO are the best candidates for the construction of mono-enzyme ABSs sensitive and selective towards Arg. Additionally, the combination of natural enzymes with appropriate nanomaterials seems to be the most optimal approach to develop advanced sensor devices with improved characteristics, namely, high stability, sensitivity, and selectivity to the target analyte [ 13 – 15 , 25 , 26 , 34 ]. To date, there are many reports on ArgO-containing ABSs which rely on the principle of detection of hydrogen peroxide as a by-product of Arg degradation.…”

Amino acid L-arginine (Arg), usually presented in food products and biological liquids, can serve both as a useful indicator of food quality and an important biomarker in medicine. The biosensors based on Arg-selective enzymes are the most promising devices for Arg assay. In this research, three types of amperometric biosensors have been fabricated. They exploit arginine oxidase (ArgO), recombinant arginase I (ARG)/urease, and arginine deiminase (ADI) coupled with the ammonium-chelating redox-active nanoparticles. Cadmium-copper nanoparticles (nCdCu) as the most effective nanochelators were used for the development of ammonium chemosensors and enzyme-coupled Arg biosensors. The fabricated enzyme/nCdCu-containing bioelectrodes show wide linear ranges (up to 200 µM), satisfactory storage stabilities (14 days), and high sensitivities (A⋅M−1⋅m−2) to Arg: 1650, 1700, and 4500 for ADI-, ArgO- and ARG/urease-based sensors, respectively. All biosensors have been exploited to estimate Arg content in commercial juices. The obtained data correlate well with the values obtained by the reference method. A hypothetic scheme for mechanism of action of ammonium nanochelators in electron transfer reaction on the arginine-sensing electrodes has been proposed. Graphical abstract

Endocrine-disrupting chemicals (EDCs) are synthetic compounds widely used in various industrial and consumer products, raising concerns about their potential adverse effects on human health and the environment. Among the numerous EDCs, Bisphenols, phthalates, and per- and poly-fluoroalkyl substances (PFAS) have attracted significant attention due to their prevalence and adverse effects. Accurately identifying and quantifying these EDCs is important for assessing exposure levels and evaluating the associated risks. This review article shed the light on recent advancements in modified electrochemical sensors and biosensors using nanomaterials, molecularly imprinted polymers (MIPs), Metal organic frameworks and nanocomposite-based electrodes, and their applicability for detecting EDCs during the past five years. The development of innovative electrode materials, optimization strategies used to increase the sensitivity and selectivity of electrochemical sensors. The challenges of real-world sample analysis are investigated as well along with possible solutions, such as matrix interference and detection limitations. Future perspectives and emerging trends in the electrochemical detection of EDCs, are also elaborated with a particular emphasis on developments in portable and miniaturized devices, multiplexed sensing platforms, and the incorporation of machine learning and artificial intelligence for better data analysis, and on-site detection.

“…Another common type of chiral substance found in food is chiral pesticides [ 2 , 3 , 4 , 5 , 6 ]. Chiral pesticides exist as one or more enantiomers with different spatial configurations, resulting in significant differences in their pharmacological effects, degradation rates, and toxicity levels [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Analyzing the residual presence of chiral pesticides in food is necessary to maximize their efficacy while minimizing their adverse effects on non-target organisms.…”

The analysis of enantiomers in food has significant implications for food safety and human health. Conventional analytical methods employed for enantiomer analysis, such as gas chromatography and high-performance liquid chromatography, are characterized by their labor-intensive nature and lengthy analysis times. This review focuses on the development of rapid and reliable biosensors for the analysis of enantiomers in food. Electrochemical and optical biosensors are highlighted, along with their fabrication methods and materials. The determination of enantiomers in food can authenticate products and ensure their safety. Amino acids and chiral pesticides are specifically discussed as important chiral substances found in food. The use of sensors replaces expensive reagents, offers real-time analysis capabilities, and provides a low-cost screening method for enantiomers. This review contributes to the advancement of sensor-based methods in the field of food analysis and promotes food authenticity and safety.
