AB  - In this work, we proposed a simple co-mixing method to fabricate magnetic 
      one-dimensional polyaniline (denoted as 1D-PANIs/MNPs). One-dimensional 
      polyanilines (1D-PANIs) and magnetic nanoparticles (MNPs) were prepared by 
      chemical oxidation and solvothermal methods, respectively. When MNPs and 1D-PANIs 
      (with mass ratio 4:1) were co-mixed and vortexed evenly in a solvent (e.g., 
      ethanol, water, acetonitrile), they could assemble into 1D-PANIs/MNPs 
      spontaneously and thus be magnetically separable. To testify the feasibility of 
      1D-PANIs/MNPs in sample preparation, it was applied as the sorbent for magnetic 
      solid phase extraction (MSPE) of fluoroquinolones (FQs) in honey samples. Under 
      optimized conditions, a rapid, convenient, and efficient method for the 
      determination of four FQs in honey samples by 1D-PANIs/MNPs-based MSPE coupling 
      with high performance liquid chromatography with fluorescence detection 
      (HPLC-FLD) was established. The limits of detection (LODs) for four FQs ranged 
      from 0.4 to 1.4 ng g(-1). The intra- and interday relative standard deviations 
      (RSDs) were less than 17.6%. The recoveries of FQs for three spiked honey samples 
      ranged from 86.3 to 121.3%, with RSDs of less than 16.3%.
