Ratiometric fluorescent probe for enantioselective detection of D-cysteine in aqueous solution

Ratiometric fluorescent probe for enantioselective detection of D-cysteine in aqueous solution

A ratiometric fluorescent probe based on a Cd2+–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 e...

Description
Summary:A ratiometric fluorescent probe based on a Cd2+–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.
