A visiblelightexcitable rhodamine based probe operates as a SCN(-) selective fluorescent "turn-on" sensor for living cell imaging with a detection limit of 0.01 muM, which is much lower than the normal SCN(-) level in the human body. A "lock" and "key" model has been proposed to explain the fluorescence enhancement of the rhodamine probe in the presence of SCN(-).
