The fluorescence of GSH\u2010capped CdTe QDs could be efficiently quenched by SCG through electron transfer from GSH\u2010capped CdTe QDs to SCG. Under optimum conditions, the response was linearly proportional to the concentration of SCG between 0.6419 and 100 \u00b5g\/mL, with a correlation coefficient (<jats:italic>R<\/jats:italic>) of 0.9964; the detection limit (3\u03b4\/K) was 0.1926 \u00b5g\/mL. The optimum conditions and the influence of coexisting foreign substances on the reaction were also investigated. The very effective and simple method reported here has been successfully applied to the determination of SCG in synthetic and real samples. It is believed that the established approach could have good prospects for application in the fields of clinical diseases diagnosis and treatment.
