A nucleophilic addition–elimination based ratiometric fluorescent probe for monitoring N₂H₄ in biological systems and actual samples

Abstract

Hydrazine (N2H4) is an important reagent in the field of fine chemical engineering. However, its accumulation in the environment and food chain could pose a great threat to food safety...

Visualization detection of mycotoxin patulin in fruit juices by a small-molecule fluorescent probe

“…33,34 Among these, the fluorescence method utilizing fluorescent probes is particularly attractive due to its simplicity, convenient visual detection, and high sensitivity. [35][36][37][38][39][40][41][42][43] Researchers have designed and applied various fluorescence probes based on antibodies, 44 aptamers, 45,46 quantum dots, 47,48 and liposomes 49 for detection of patulin in food samples. However, many of the fluorescent probes reported in the literature suffer from complex and time-consuming fabrication or involve intricate operation conditions and procedures.…”
