A fluorescent probe for colorimetric detection of bisulfite and application in sugar and red wine.

ABSTRACT: A new fluorescent probe made from (E)-2-(benzo[d]thiazol-2-yl)-3-(6-hydroxynaphthalen-2-yl) acrylonitrile (Probe 1) was synthesized for the determination of bisulfite concentrations in real food samples (red wine and sugar). Adding bisulfite to a Probe 1 solution caused a marked decrease in fluorescence intensity and a visual color change from yellow to light yellow. This distinct color response indicates that Probe 1 could be used as a visual sensor for bisulfite. Probe 1 can detect bisulfite quantitatively in the range 0-400 ?M with a detection limit of 0.10 ?M. This makes Probe 1 a convenient signaling instrument for determining bisulfite levels in sugar and red wine samples.
