Abstract

Water-soluble luminescent CdSe quantum dots surface-modified with 2-mercaptoethane sulfonate were synthesized for the selective determination of free cyanide in aqueous solution with high sensitivity (detection limit of 1.1 × 10−6 M), via analyte-induced changes in their photoluminescence after photoactivation.
