A Visible Colorimetric Fluorescent Probe for Hydrogen Sulfide Detection in Wine
Figure 1
(a) Time-dependent fluorescence spectra of probe 1 (10 μM) in the presence of H2S (200 μM) in phosphate buffer saline (PBS; pH 7.4) with DMSO (v/v, 3 : 1) at 37°C; (b) time-dependent fluorescence intensity changes of probe 1 (10 μM) in the presence of H2S (200 μM) at 504 nm. λex = 307 nm, λem = 504 nm, and slit width = 5 nm/5 nm. The test was repeated 3 times.
