A carbazole-benzothiazole-based fluorescent probe embedded in paper, cellulose, and chitosan sensors for visual and rapid detection of bisulfite in food samples.

Bisulfite (HSO3-) is widely used as a food additive, yet its excessive residue poses potential health risks. Herein, a novel fluorescent probe TC-FV-BT was developed for the detection of HSO3-. Upon addition of HSO3-, the nucleophilic addition disrupted the π-conjugation of the probe, giving rise to a distinct fluorescence enhancement with bright orange emission. TC-FV-BT exhibited a rapid response, a low detection limit of 0.077 μM, and excellent selectivity. The sensing mechanism was confirmed by 1H NMR titration, HRMS, and DFT calculations. Furthermore, TC-FV-BT was successfully immobilized onto paper, cellulose acetate (CA), and chitosan (CS) film substrates to construct a portable visual detection platform, which was applied to the analysis of HSO3- in ten complex food matrices. Notably, the CS film-based sensor displayed superior anti-interference performance in high-oil and high-pigment samples. This work provides a versatile and practical platform for on-site rapid monitoring of HSO3- in food safety applications.

A nopinone-based ratiometric fluorescent probe for rapid detection of GSH and its applications in the environment and biological imaging.

Herein, we have developed a novel ratiometric fluorescent probe through rational design and synthesis, named 2-((5-(4-(3,3-dimethyl-1,2,3,4-tetrahydro-2,4-methoxyacridin-9-yl) phenyl) thiophen-2-yl) methylene)-1H-indene-1,3 (2H)-dione, abbreviated as TA-PT-ID. TA-PT-ID is based on the nopinone skeleton and utilizes a Michael addition reaction as the GSH recognition mechanism. TA-PT-ID exhibits excellent photophysical properties, including a rapid response to GSH (within 1 min), a good linear correlation (R2 = 0.9919), and a low detection limit of 50 nM. TA-PT-ID was successfully applied to the detection of GSH in soil and water samples. Furthermore, ratiometric imaging of endogenous GSH was achieved using TA-PT-ID in HeLa cells, RAW264.7 cells, and zebrafish. In summary, TA-PT-ID provides a powerful new tool for the real-time detection of GSH in complex environments, and its rapid response and broad pH adaptability make it highly promising for applications in biological imaging and environmental monitoring.
