## Abstract

MXene, owing to its high electrical conductivity, large specific surface area, and abundant surface functional groups, has been widely applied in the detection of foodborne pathogens. Therefore, it is necessary to review recent developments in the emerging material MXene for the detection and killing of foodborne pathogens, which is expected to facilitate the further development and utilization of MXene. This work comprehensively reviews advances in MXene applications for detecting and killing foodborne pathogens. Firstly, applications of MXene in electrochemical sensors, surface-enhanced Raman scattering (SERS), fluorescence platforms, and fluorescence–electrochemical dual-mode sensing systems are introduced. Subsequently, the sterilization mechanisms of MXene are described, followed by a detailed explanation of its practical applications in active food packaging, surface modification of food processing equipment, and instant sterilization techniques. Finally, conclusions, challenges, and future prospects in the area of MXene for the detection and killing of foodborne pathogens are discussed in depth. Significantly, this review uniquely summarizes applications of MXene in the detection and sterilization of foodborne pathogens, offering new perspectives on its use in food safety.
