“…The LSPR peak shift of the proposed fiber end-face aptasensor showed a good linear relationship with the logarithmic concentration of FB 1 (R 2 = 0.9817), and the LOD was 0.17 ng mL −1 . Jaroon’s research team designed an unlabeled colorimetric aptasensor, which exploited the selective interaction between the aptamer and AFM 1 , leading to structural changes while allowing for the aggregation of AuNPs induced by NaCl [ 206 ]. The solution’s color changes resulting from the LSPR peak shift of the aggregated AuNPs can be directly quantitatively measured using colorimetry.…”

Trace amounts of mycotoxins in food matrices have caused a very serious problem of food safety and have attracted widespread attention. Developing accurate, sensitive, rapid mycotoxin detection and control strategies adapted to the complex matrices of food is crucial for in safeguarding public health. With the continuous development of nanotechnology and materials science, various nanoscale materials have been developed for the purification of complex food matrices or for providing response signals to achieve the accurate and rapid detection of various mycotoxins in food products. This article reviews and summarizes recent research (from 2018 to 2023) on new strategies and methods for the accurate or rapid detection of mold toxins in food samples using nanoscale materials. It places particular emphasis on outlining the characteristics of various nanoscale or nanostructural materials and their roles in the process of detecting mycotoxins. The aim of this paper is to promote the in-depth research and application of various nanoscale or structured materials and to provide guidance and reference for the development of strategies for the detection and control of mycotoxin contamination in complex matrices of food.
