A water-soluble fluorescence probe (TF) derived from fluorescein has been developed. This probe can be used to detect ClO− and Cd2+ under physiological condition based on oxidation and coordination reactions, exhibiting almost 64-fold and 4-fold fluorescence enhancement. The experimentally observed changes in the structure and electronic properties of the probe in the presence of ClO− and Cd2+ were...
On the basis of fluorescence resonance energy transfer (FRET), a new rhodamine derivative (DRh) was synthesized as a ratiometric fluorescent probe for detecting Hg2+ in water and living cells samples. The recognition properties of the probe DRh with metal ions had been investigated in H2O/CH3CN (9:1, v/v; Tris-HCl 50mmolL−1; pH=7.0) solution by the UV–Vis spectrophotometry and the fluorescence spectrophotometry...
