Abstract: In this paper, quantum dot (QD)-based molecularly imprinted polymer (MIP) was fabricated and successfully utilized as a fluorescent probe for highly selective and sensitive detection of carbofuran in water samples. The MIPs were synthesized followed by a multi-step swelling and polymerization method, and then labeled with CdSe/ZnS QDs via gradual solvent evaporation. Then the prepared QDs-MIP microspheres were introduced to flow cytometry by virtue of their good dispersibility in water, and fast adsorption and desorption. Under optimized conditions, the fluorescence intensity of QDs-MIP decreased linearly with the increasing of carbofuran in the concentration range of 1 - 20 μg L-1 (R2 > 0.99) and it can detect down to 0.2 μg L-1 of carbofuran. This method was simple, selective and applied successfully to the optosensing of trace carbofuran in water samples with good recoveries ranging from 94.1 ± 3.7 to 98.4 ± 4.5%
