  • Title: NBD-based colorimetric and ratiometric fluorescent probe in NIR for bisulfite.
    Author: Li F, Zhai SM, Xian-Yu JJ, Zhao BX, Lin ZM.
    Journal: Talanta; 2024 May 01; 271():125684. PubMed ID: 38262131.
    Abstract:
    This work presented a FRET-ICT based fluorescent probe (named NTC) composed of coumarin-benzothiazole as the acceptor and 4-nitrobenzo[c][1,2,5] oxadiazole (NBD) as the donor for the detection of SO2 derivatives in NIR. Probe NTC possessed superior performance including selectivity, quickly response toward SO32-/HSO3- and high energy transfer efficiency (94 %). The test strips provided a simple and effective tool in detecting the presence of bisulfite. Besides, NTC was applied to test the sulfur dioxide derivatives in food samples and cells.
