The interaction between the MPA\u2013capped CdTe QDs and salicylic acid was studied using fluorescence spectroscopy and some parameters that could modify the fluorescence were investigated to optimize the measurements. Under optimum conditions, the quenched fluorescence intensity of MPA\u2013capped CdTe QDs was linearly proportional to the concentration of salicylic acid in the range of 0.5\u201340 \u00b5g mL<jats:sup>\u20131<\/jats:sup> with a coefficient of determination of 0.998, and the limit of detection was 0.15 \u00b5g mL<jats:sup>\u20131<\/jats:sup>. The method was successfully applied to the determination of salicylic acid in pharmaceutical products, and satisfactory results were obtained that were in agreement with both the high pressure liquid chromatography (HPLC) method and the claimed values. The recovery of the method was in the range 99 \u00b1 3% to 105 \u00b1 9%. The proposed method is simple, rapid, cost effective, highly sensitivity and eminently suitable for the quality control of pharmaceutical preparation. The possible mechanisms for the observed quenching reaction was also discussed.
