Twenty five molecular imprinting prepolymerization systems were performed based on COMPASS force field to optimize the imprinting shell of the fluorescent sensor. The result revealed that the optimum mole ratio of 4-Nitrophenol (4-NP), 3-aminopropyltriethoxysilane (APTES) and tetraethylorthosilicate (TEOS) in this system was 10:20:80, which was the most stable between template and functional monomer cluster. Uniform magnetite nanaocrystals prepared by hydrothermal method were subsequently embedded in the spherical silica using the reverse microemulsion polymerization. The magnetic silica microspheres were modified with amide groups to adsorb the mercaptoacetic acid capped CdTe nanocrystals. Finally, according to the results of molecular dynamics simulation, the imprinting shell was anchored on the multifunctional nanocomposites. Under the optimal conditions, a linear relationship between relative fluorescence intensity and concentration of 4-NP was obtained covering the concentration range from 5 to 150 ng/mL with a limit of detection of 1 ng/ml. The feasibility of the fluorescent sensor was successfully evaluated through the analysis of 4-NP in river water. The recoveries were from 98.7% to 101.2%, and the relative standard deviation ranged from 1.5% to 2.4%.
