In this work, magnetic quantum dots molecularly imprinted polymers were synthesized, which were based on ZnS and magnetic Fe(3)O4. The polymers had a spherical shape and a core-shell structure and exhibited a magnetic strength of 17.20 emu g(-1) and optical stability. After the experimental conditions were optimized, the fluorescence intensity showed a linear dependence with concentration from 5.0 mu mol L-1 to 50 mu mol L-1, with R-2 = 0.9960. Upon optimizing the experimental conditions, the linear dependence of fluorescence intensity with concentration ranged from 5.0 mu mol L-1 to 50 mu mol L-1, with a detection limit of 0.08 mu mol L-1. Furthermore, the MQDs-MIPs were successfully used for the detection of a tap water sample. With three spiking concentration levels, the recovery rate of each experiment was from 99.45 to 103.4%, with a relative standard deviation from 1.97 to 3.37%. This study provides a promising strategy for fabricating magnetic fluorescence molecular imprinted polymers with highly selective recognition ability.
