Tartaric acid (TA), a key organic acid in grapes and wine, is closely linked to taste quality and human health, making its accurate detection highly important. In this work, we report a borophene/poly(3-methylthiophene) (P3MTP) hybrid electrode fabricated via solvent-mediated exfoliation of borophene and electropolymerization of P3MTP on indium tin oxide (ITO) glass. The modified electrode was evaluated by cyclic voltammetry and interference studies, showing a wide linear detection range (5–300 μM), a low detection limit (LOD) (4 μM), and high selectivity toward TA. The sensor also demonstrated excellent stability. In addition, the sensor demonstrated reproducibility with a relative standard deviation (RSD%) of 1.70%. Furthermore, molecular simulations clarified the interaction mechanism between TA, borophene, and P3MTP, explaining the observed electrochemical interaction. These findings highlight the potential of borophene-polymer hybrids as efficient sensing platforms for food quality control and health monitoring.

The field of gas sensing has witnessed rapid and transformative progress through the integration of 2D materials, which exhibit unique physicochemical properties ideal for next‐generation sensor platforms. These atomically thin materials possess exceptional features such as a high surface exposure, tunable conductivity, and superior mechanical adaptability, making them particularly effective in detecting trace levels of various gases. Their minimal thickness and intrinsic electronic versatility enable enhanced performance metrics, including improved sensitivity, fast response times, and better selectivity. This review explores the recent innovations in gas sensor technologies, leveraging a wide range of 2D materials and their composite structures. Emphasis is placed on the roles of graphene, transition metal dichalcogenides, MXenes, metal oxides, elemental 2D materials like Xenes (e.g., borophene), and their functional hybrids. In addition to showcasing the versatile capabilities of these materials, this review also examines current challenges and limitations. It aims to offer a comprehensive perspective on the potential of 2D‐based systems to transform gas‐sensing approaches and to inform future research in this rapidly advancing field.

Histamine, a biogenic amine (BA), plays a significant role in various pathophysiological processes and is present in food supplies, serving as an indicator of freshness and microbial degradation. It is a major cause of food poisoning outbreaks, triggering allergic inflammatory responses. Detecting histamine in food is crucial because its toxic threshold does not affect the food's taste, making contaminated items appear normal. To address this challenge, label‐free and bioactive‐free electrochemical sensors utilizing molecularly imprinted polymers (MIPs) offer the desired selectivity, scalability, and efficiency. MIPs are synthetic materials designed to mimic biological receptors. This paper reviews a decade of research on MIP‐assisted electrochemical sensors for histamine detection, focusing on their scalability, robustness, speed, and selectivity. The review critically analyzes the performance of these sensors in detecting histamine in food, beverages, human serum, and body diagnostics. Additionally, the current understanding of the physiological effects of endogenous and ingested histamine is reviewed, highlighting both established and emerging methods for its quantification in food and health management. The potential for transforming healthcare delivery through personalized Point‐of‐Care (POC) systems, integrated with Artificial Intelligence (AI) and Internet‐of‐Medical Things (IoMT) technologies, is also discussed.
