Abstract: A sensitive optical sensor, using a molecularly imprinted film on CdTe quantum dots (CdTe QDs), is developed for the selective detection of prilocaine. At the first step of this work, water-soluble thioglycolic acid capped CdTe QDs (TGA capped-CdTe QDs) were prepared using refluxing method. At the next step, a thin film of silica was formed, by reverse microemulsion technique, on the surface of CdTe quantum dots. Finally, molecularly imprinted polymer embedded CdTe QDs were obtained. In this step, 3-aminopropyltriethoxysilane (APTS) and tetraethoxysilane (TEOS) were applied as a functional monomer and a cross linker, respectively. Different variables affecting the optical signal were optimized. Under optimal conditions, the dynamic range of the optical sensor was 5.5-260.0 nmol L-1 prilocaine with a detection limit as low as 0.6 nmol L-1. The relative standard deviations of 5.3% and 7.5% for 126 and 35 nmol L-1 prilocaine (n = 3) were observed. The response of the optical sensor on common species in biological media was investigated. The results confirmed the good selectivity of the sensor for the measurement of prilocaine
