Special Issue Information

Dear Colleagues,

Toxins are poisonous substances of biological origin, produced by a variety of organisms including fungi, bacteria, plants, algae, and certain animals, which may contaminate food at specific concentrations and adversely affect human and animal health. The application of advanced analytical methods, including chromatographic methods, mass spectrometry, optical spectroscopic and imaging techniques, immunoassays, and molecular methods, plays a key role in the detection and identification of toxins in food, particularly within the field of food forensics. These methods are widely applied in food safety control, quality assurance, regulatory monitoring, and the investigation of food fraud and contamination incidents. This Special Issue aims to highlight the latest research on innovative detection approaches for toxin risk factors in food, including advanced instrumental techniques.  We welcome original research and review articles covering diverse analytical methods used in food toxin detection.

The sensitive and efficient detection of ochratoxin A (OTA) is critical for protecting agricultural ecosystems and public health. A dual-mode plasmonic colorimetric/photothermal aptasensor, based on a Mn2+-powered DNA walker for mediating gold nanobipyramid (AuNB) growth, is proposed for OTA detection in this study. In sensing the target OTA, the walking DNA (W-DNA) on the magnetic walker probe was independent and then the environment-friendly Mn2+ powered the generation of DNAzyme, where abundant thiol-modified DNA (DNA-SH) was produced by autonomous walking. The positively related DNA-SH level could mediate AuNB growth and reflect dual-mode plasmonic signals. Ultrasensitivity is demonstrated with a limit of detection (LOD) value of 48.6 pg mL−1 for colorimetric mode and 37.6 pg mL−1 for photothermal mode. The aptasensor exhibited high specificity (with cross-reactivity values below 6.2% for other analytes) and high reliability for OTA detection. The requisite practicability and accessibility are verified via its application in agricultural byproduct samples. The findings of this study offer an alternative and efficient biosensing pathway for improving detection performance, enabling green, enzyme-free, homogeneous, and dual-mode strategies for monitoring other pollutants.
