Fluorescence detection of adenosine-5′-triphosphate and alkaline phosphatase based on the generation of CdS quantum dots.

Highlights: [•] Cd2+ reacts with S2− to generate fluorescent CdS QDs with ATP. [•] ATP can be hydrolyzed by the enzymatic dephosphorylation of ALP. [•] Fluorescent CdS QDs could not be generated in the presence of ALP. [•] The analysis system was successfully applied to assay ATP and ALP. [ABSTRACT FROM AUTHOR]
