AB  - This paper reports a facile and general method for preparing an imprinted polymer 
      thin shell with Mn-doped ZnS quantum dots (QDs) at the surface of silica 
      nanoparticles by stepwise precipitation polymerization to form the 
      highly-controllable core-shell nanoparticles (MIPs@SiO2-ZnS:Mn QDs) and 
      sensitively recognize the target 2,4-dichlorophenol (2,4-DCP). Acrylamide (AM) 
      and ethyl glycol dimethacrylate (EGDMA) were used as the functional monomer and 
      the cross-linker, respectively. The MIPs@SiO2-ZnS:Mn QDs had a controllable shell 
      thickness and a high density of effective recognition sites, and the thickness of 
      uniform core-shell 2,4-DCP-imprinted nanoparticles was controlled by the total 
      amounts of monomers. The MIPs@SiO2-ZnS:Mn QDs with a shell thickness of 45 nm 
      exhibited the largest quenching efficiency to 2,4-DCP by using the 
      spectrofluorometer. After the experimental conditions were optimized, a linear 
      relationship was obtained covering the linear range of 1.0-84 mumol L(-1) with a 
      correlation coefficient of 0.9981 and the detection limit (3sigma/k) was 0.15 mumol 
      L(-1). The feasibility of the developed method was successfully evaluated through 
      the determination of 2,4-DCP in real samples. This study provides a general 
      strategy to fabricate highly-controllable core-shell imprinted polymer-contained 
      QDs with highly selective recognition ability.
