AB  - In this work, a novel microextraction technique using molecularly imprinted 
      polymer-coated multi-walled carbon nanotubes (MIP-MWCNTs) in electromembrane 
      extraction (EME) procedure is described. The method in combination with HPLC-UV 
      was utilized to determine naproxen, as an acidic model drug, in urine, plasma and 
      wastewater samples. For this purpose, MIP-MWCNTs were placed in the pores of 
      polypropylene hollow fiber. The MIP-MWCNTs-EME method has the advantages of high 
      selectivity and cleanup of MIP along with high enrichment ability of the EME in a 
      single step extraction. Continuing with the research, optimization of the factors 
      affecting the migration of naproxen from sample solutions to MIP-MWCNTs sites and 
      then into the lumen of hollow fiber was explored. Under the optimized conditions, 
      the limit of detection (LOD) of the developed method was calculated to be 
      0.3mugL(-1). All relative standard deviations (RSDs) were lower than 3%. Linearity 
      of the method was obtained within the range of 1-1000mugL(-1) with the coefficient 
      of determination (r(2)) being higher than 0.999. Under the optimized conditions, 
      an extraction recovery of 66% was obtained, which corresponded to a 
      preconcentration factor of 88. Finally, the developed method was satisfactorily 
      used to determine naproxen in urine, plasma and wastewater samples.
