Colorimetric and fluorescent detection of biological thiols in aqueous solution
摘要:
A new calorimetric and fluorescent probe, 2-(2,4-dinitrostyryl)-1,3,3-trimethyl-3H-indolium iodide (DTI), for selective and sensitive detection of biological thiols is reported. In aqueous solution at physiological pH 7.4, biological thiols react with DTI via Michael addition to give the brownish red adduct concomitant with fluorescence emission decrease.
