| Abstract: | A new type of molecularly imprinted-quantum dot nanostructure polymers (MIP-QDs) for Bisphenol A (BPA), which combines the high selectivity of molecularly imprinted polymers and excellent fluorescence properties of QDs, is presented using the surface grafting technique. The MIP-QDs are firstly characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and selective fluorescence quenching properties in different solutions. Under the optimal conditions (water:ethanol (4:6, V/V), pH 5.0, NaCl 3.5%), a good linear relationship with a correlation coefficient of 0.9983 is obtained in the range of 0.002~10.0 mg·L-1. The detection limit of BPA in seawater samples is set to be 0.75 μg·L-1. Satisfying recoveries ranging from 96.8% to 102.8% and the RSD below 7.4% are obtained for the seawater samples at three spiked levels of BPA. The results demonstrate that the developed MIP-QDs approach possesses most satisfactory fluorescence quenching properties. |
