This review provides an overview of the latest developments using small-molecule-based ratiometric fluorescent sensors designed for cadaverine detection.
Reticular frameworks, including MOFs and coordination polymers, enable food spoilage detection by sensing volatile and biogenic amines through chromogenic and fluorogenic pathways.
This paper highlights the use of conjugated organic materials to construct sensors for the detection of biogenic amines released from decomposing food stuffs.
A Schiff base IBS was obtained by condensing equimolar amounts of 4-(diphenylamino)benzaldehyde and 1,2-diaminobenzene. It was employed for the cascade fluorescence ‘off–on’ detection of Fe3+ and biogenic amines.
A naphthylamine-based fluorescence sensor (TP) detects biogenic amines (spermine and spermidine) in natural water and food samples by inducing turn-on fluorescence. The receptor–amine complex could detect formaldehyde in solution and the vapour phase
