Detection of HSO₃^-: A Rapid Colorimetric and Fluorimetric Selective Sensor for Detecting Biological SO₂ in Food and Living Cells.

ABSTRACT: A rapid fluorescent probe based on the conjugate of chromone and benzothiazole moiety was presented, which could selectively respond to HSO₃^- over other common anions and thiols. The function of the probe relies on nucleophilic addition to break down the π-conjugation. The probe can be used as a signal tool to determine HSO₃^- levels in sugar-based food and living cells.
