In pH\u20095.4 sodium phosphate buffer medium, the interaction between GSH\u2010CdTe\/CdS QDs and sanguinarine (SA) was investigated by spectroscopic methods, including fluorescence spectroscopy and ultraviolet\u2010visible absorption spectroscopy. Addition of SA to GSH\u2010CdTe\/CdS QDs results in fluorescence quenching of GSH\u2010CdTe\/CdS QDs. Quenching intensity was in proportion to the concentration of SA in a certain range. Investigation of the quenching mechanism, proved that the fluorescence quenching of GSH\u2010CdTe\/CdS QDs by SA is a result of electron transfer. Based on the quenching of the fluorescence of GSH\u2010CdTe\/CdS QDs by SA, a novel, simple, rapid and specific method for SA determination was proposed. The detection limit for SA was 3.4\u2009ng\/mL and the quantitative determination range was 0.2\u201340.0\u2009\u00b5g\/mL with a correlation coefficient of 0.9988. The method has been applied to the determination of SA in synthetic samples and fresh urine samples of healthy human with satisfactory results.
