Description
FGGH is a water-soluble peptide-based probe. FGGH performs the sequential detection of Cu2+ and S2- by fluorescence and colorimetry with high sensitivity (LOD: 1.42 and 22.2 nM for Cu2+ and S2-, respectively) (Ex=488 nm, Em=525 nm), and images both two ions in living cells and zebrafish models with low cytotoxicity. FGGH can be used for in vivo imaging and environmental pollution monitoring research[1]
