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.
In addition, the immobilization of recognition elements is of concern due to the complex and varied food matrices. Antibodies, nanoantibodies, aptamers, and molecularly imprinted polymers (MIPs) are critical components of emerging biosensors that could improve the selectivity and robustness of the sensing platforms vital to the food industry. In particular, the development and application of aptamers and MIPs significantly reduce the cost of rapid detection technology, thus facilitating the promotion of these detection technologies in the market. Overall, developing novel detection methods not only enhances the law enforcement ability of society and the government by improving detection sensitivity but also promotes companies and factories to regulate themselves to ensure food safety, thus ensuring food safety, enabling the food safety control system to be continuously improved, and promoting the sustainable development of the food industry.
This Research Topic aims to provide recent advances in fabricating high-performance sensing platforms for organic pollutant analysis in food. We welcome research articles that focus on using functional nanomaterials in sensing, the construction of recognition strategy, and signal amplification, especially the fabrication of biosensors, such as microfluidic chips. Theoretical studies on the interaction and orientation of the adsorbates on the functional material surface are also welcome. The specific topic includes but are not limited to:
• Functional nanomaterials for the fabrication of sensors
• The screening aptamer against small molecules
• The preparation of MIPs against small molecules
• Determination of organic pollutants by colorimetry, fluorometry, Surface Enhanced Raman Spectroscopy, electrochemistry, and photoelectrochemistry
