a Fluorescence spectra of probe BCD (60 µM) in the presence of other species (1 mM) in the DMF-Hepes buffer (8/2, v/v, pH = 7.4), λex = 463 nm. Inset: color of the solution containing BCD (60 µM) before and after the addition of Cys(1.4 mM), Hcy(1.4 mM), GSH (1.4 mM) in the DMF-Hepes buffer (8/2, v/v, pH = 7.4) under 365 nm UV light. b Fluorescence spectra of probe BCD (60 µM) in the presence of other species (400 µM) in the DMF-Hepes buffer (7/3, v/v, pH = 7.4), λex = 407 nm. Inset: color of the solution containing BCD (60 µM) before and after the addition of N2H4 (10 mM) in the DMF-Hepes buffer (7/3, v/v, pH = 7.4) under 365 nm UV light
