Hydrogen peroxide is a widely used agent in the food industry for its sterilization, packaging, and transportation capabilities. However, its excessive concentration can lead to adverse health effects, especially in gastrointestinal conditions. As a result, it is crucial to detect its presence in food products, particularly milk. To address this need, we have developed a state‐of‐the‐art MXene‐based ECL system that can detect low‐concentration hydrogen peroxide levels with high sensitivity and accuracy. Our system incorporates 2D MXene structures, which not only enhance electrode conductivity but also form a complex with Ni/Sm‐LDH (layered double hydroxide) that enables detection across a broad linear range of 0.05–2 ppm in real samples. Furthermore, we have successfully lowered the detection limit to an impressive 0.005 ppm. With this innovative approach, we can ensure the safety and quality of food products, making it a significant breakthrough in the food industry. [ABSTRACT FROM AUTHOR]
