Outline of Final Research Achievements |
This research focused on the bio-analytical application of the fluorescent probes by exploiting the AM-contact (arena-metal ion) emission shift, which is induced by the direct contact between metal ion and fluorophore within their Wan-der Waals radii. In this research we successfully applied a cadmium ion complex to the ratiometric detection of hydrogen sulfide, an bioactive gas, in living cells. We also designed the fluorescent probes appended with a cyclic ligand, which selectively shows a large emission shift upon binding with silver ion. We also successfully applied AM-contat sensing to the ratiomettic detection of zinc ion by the elaborated design of the metal binding unit.
