Abstract:Agricultural products, food and feed are often contaminated by many mycotoxins. The development of high-throughput mycotoxin rapid detection products, which are used to detect multiple toxins is one of the key directions. Among the current mainstream rapid detection products, traditional paper-based sensors with colloidal gold as signal markers are mostly used to detect a single toxin, with limited information and low sensitivity. The multi-toxin paper-based sensor uses multi-toxins to couple multi-antigens, which is lower in cost and time-consuming, but the detection sensitivity is affected by the change of the test sample liquid volume. In recent years, paper-based sensors constructed with advanced materials such as precious metal nanoparticles, quantum dots, carbon nanomaterials, up-conversion particles, lanthanide metal nanoparticles, which can improve the performance of multi-toxin paper-based sensors. And they have gradually become a research for hot spot of rapid detection of multiple mycotoxins. The author summarized the detection principle and composition of multiplexed paper-based sensors, and then reviewed the applications of paper-based sensors based on advanced materials reported in the past years for simultaneous detection of multiple mycotoxins, with a view to rapid and joint detection of multiple mycotoxins.
