Nanomaterial-enabled sensing of paraquat in food and environmental matrices: mechanisms, materials, and analytical challenges.

Paraquat (PQ), a highly toxic herbicide banned in several countries yet still widely used globally, poses severe threats to human health and ecosystems through acute poisoning and chronic exposure via contaminated food and water. Despite numerous analytical methods, rapid, sensitive, and field-deployable detection rema...
