A New Quinone Based Fluorescent Probe for High Sensitive and Selective Detection of Biothiols and Its Application in Living Cell Imaging

<p>Change of fluorescence spectra with time for the reactions of DDQ and biothiols in the ethanol system. (a) DDQ (10 <i>μ</i>M) with Hcy (0.1 mM), (inset) change of fluorescence intensity with time at 467 nm. (b) DDQ (10 <i>μ</i>M) with GSH (1 mM), (inset) change of fluorescence intensity with time at 494 nm.</p>
