a Fluorescence spectral changes of BCD (60 µM) toward different concentrations of Cys in the DMF-Hepes buffer (8/2, v/v, pH = 7.4). b Linear responses of fluorescent intensity at 502 nm to varying Hcy concentration. c Fluorescence spectral changes of BCD (60 µM) toward different concentrations of Hcy in the DMF-Hepes buffer (8/2, v/v, pH = 7.4). d Linear responses of fluorescent intensity at 479 nm to varying Cys concentration. e Fluorescence spectral changes of BCD (60 µM) toward different concentrations of GSH in the DMF-Hepes buffer (8/2, v/v, pH = 7.4). f Linear responses of fluorescent intensity at 476 nm to varying GSH concentration
