An aryl-thioether substituted nitrobenzothiadiazole probe was synthesized and employed to detect cysteine and homocysteine selectively in living cells. Interestingly, both cysteine (Cys) and homocysteine (Hcy) promote an enhancement of the fluorescence intensity of the probe at pH 7.4 while only Cys gives rise to this enhancement under weakly acidic conditions (pH 6.0).
