A water soluble FRET-based ratiometric chemosensor for Hg(<scp>ii</scp>) and S²⁻applicable in living cell staining

Abstract

A new water soluble rhodamine-based ratiometric dual ‘off–on–off’ probe can selectively detect Hg²⁺ions in ppb level through time dependent FRET process with reversibility in presence of S²⁻anions.
