Advancing detection of fungal and mycotoxins contamination in grains and oilseeds: Hyperspectral imaging for enhanced food safety.

Grains and oilseeds, including maize, wheat, and peanuts, are essential for human and animal nutrition but are vulnerable to contamination by fungi and their toxic metabolites, mycotoxins. This review provides a comprehensive investigation of the applications of hyperspectral imaging (HSI) technologies for the detection of fungal and mycotoxins contamination in grains and oilseeds. It explores the capability of HSI to identify specific spectral features of contamination and emphasized the critical role of sample properties and sample preparation techniques in HSI applications.

Electrochemiluminescence detection of diazinon in vegetables based on the synergistic interaction of WO dots with Au@SiO nanocapsules.

In this work, a simple synthesis of low-toxicity transition metal material of WO dots was used as a co-reactant with Au@SiO as a core-shell material and a signal amplification factor to collaboratively promote Ru(bpy) electrochemiluminescence (ECL) for the construction of a highly sensitive aptasensor for the detection of diazinon (DZN) in vegetables. Electrodes modified with multi-walled carbon nanotubes-chitosan composite membranes (MWCNTs-CS) were used to load and immobilize more Ru(bpy).can load more Ru(bpy).
