Special Issue Information
Dear Colleagues,
Food safety is a major issue because of the prevalence of food contaminants, toxins, and other potentially harmful substances. Therefore, the development of rapid and effective detection methods is essential to ensure food safety. However, traditional detection methods usually require precise equipment, professional operators, and complex operation steps, meaning that it is hard to meet the requirements of rapid analysis. Recently, biosensors have been increasingly applied in food safety analysis due to their advantages of simple operation, fast response, and portability. Emerging biosensors (such as optical and electrochemical) integrated with portable detection devices may provide a promising tool for on-site detection of food contaminants and toxins.
This Special Issue, entitled “Application of Biosensors on the Detection of Food Contaminants and Toxins”, aims to collect high-quality research focusing on the latest advances and biosensing technologies for food safety detection. We encourage the submission of original high-quality research papers and comprehensive reviews related to the applications of biosensors in the detection of food contaminants and toxins.

Abstract: Furfural is an essential compound contributing to the distinctive flavor of sauce-flavored Baijiu. However, traditional detection methods are hindered by lengthy and complex sample preparation procedures and the need for expensive equipment. Therefore, there is an urgent need for a new approach that allows rapid detection. In this study, we developed a novel Surface-enhanced Raman spectroscopy (SERS) substrate by constructing MXene (Ti3C2TX) @Ag nanoparticles (Ag NPs) through an electrostatic self-assembly method. The MXene (Ti3C2TX) @Ag NPs were successfully fabricated, featuring uniformly adsorbed NaCl-treated Ag NPs on the surface of MXene (Ti3C2TX), creating high-density distributed SERS “hot spots“. The prepared substrate demonstrated excellent sensitivity, uniformity, repeatability, and long-term stability, with a low detection limit of 10-9 M for R6G (Rhodamine 6G) and an enhancement factor of up to 7.08×105. When applied for in situ SERS detection of furfural in Baijiu, the detection limit reached as low as 1 mg/L. Overall, the proposed method offered rapid, low-cost, and sensitive quantitative analysis, which is significant not only for detecting furfural in Baijiu but also has the potential for identifying hazardous substances and distinguishing between authentic and counterfeit Baijiu products.
