title: Ratiometric fluorescent probe for enantioselective detection of D-cysteine in aqueous solution.
abstract: A ratiometric fluorescent probe based on a Cd(2+)-ACAQ complex was designed and demonstrated for the chemo- and enantioselective detection of cysteine in 99:1 buffered HEPES:ACN solutions. Under the measuring conditions, the sensor demonstrates high selectivity toward Cys against Hcy and GSH, and an enantioselectivity of 3.35 can be achieved for antipodal forms of Cys.
