Abstract
Cutting-edge advancements in sensing technologies have positioned molybdenum disulfide (MoS 2 ) as a transformative material for detecting contaminants in food samples. Leveraging its exceptional electrical, optical, and catalytic properties, MoS 2 -based sensing platforms have demonstrated remarkable potential in identifying a wide range of foodborne hazards, including pathogens, pesticides, and allergens. This review explores the latest developments in MoS 2 -enabled sensing systems, emphasizing their ability to synergistically combine electrochemical sensitivity and optical responsiveness for unparalleled detection accuracy and efficiency. The unique two-dimensional structure of MoS 2 , with its high surface area and tunable properties, enhances sensor specificity and sensitivity, enabling rapid and reliable contaminant detection in complex food matrices. While challenges such as long-term stability, scalability, and signal interference remain, emerging strategies like hybrid nanocomposite engineering and machine learning-assisted data analysis offer promising solutions.
