Analyzing organic pollutants in food, such as pesticides, pathogenic bacteria, and toxins is critical to ensuring global food security. Implementing reliable, effective, and rapid screening methods can ensure the accuracy of analytical results, improve the efficiency of analysis, and contribute to strengthening food safety supervision, thus promoting the sustainable development of the food system. In recent years, efficient sensing methods have attracted extensive attention, including colorimetry, fluorimetry, surface-enhanced Raman spectroscopy, electrochemistry, and photoelectrochemistry. In addition, and more importantly, the rapidly emerging research field of nanotechnology to deploy nanomaterials provides exciting new possibilities for enhancing the performance of analytical methods (e.g., lower detection limit, wider detection linear range) in bioanalytical and biotechnological applications. Therefore, applying nanomaterials to sensing platforms is essential for efficient sensor development.
