Abstract

Cutting-edge advancements in sensing technologies have positioned molybdenum disulfide (MoS₂) as a transformative material for detecting contaminants in food samples. Leveraging its exceptional electrical, optical, and catalytic properties, MoS₂-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 MoS₂-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 MoS₂, 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. This review underlines the transformative potential of MoS₂-based sensing platforms in revolutionizing food safety monitoring, ensuring public health protection, and paving the way for sustainable and cost-effective detection technologies.
