AB  - A novel fluorescence sensing strategy for determination of atrazine in tap water 
      involving direct competition between atrazine and 5-(4,6-dichlorotriazinyl) 
      aminofluorescein (5-DTAF), and which exploits magnetic molecularly imprinted 
      polymer (MMIP), has been developed. The MMIP, based on Fe3O4-chitosan 
      nanoparticles, was synthesized to recognize specific binding sites of atrazine. 
      The recognition capability and selectivity of the MMIP for atrazine and other 
      triazine herbicides was investigated. Under optimal conditions, the competitive 
      reaction between 5-DTAF and atrazine was performed to permit quantitation. 
      Fluorescence intensity changes at 515 nm was linearly related to the logarithm of 
      the atrazine concentration for the range 2.32-185.4 muM. The detection limit for 
      atrazine was 0.86muM (S/N=3) and recoveries were 77.6-115% in spiked tap water 
      samples.
