AB  - Microcystins (MCs), which are produced by eruptive cyanobacteria, seriously 
      threaten the health of humans for their poisonousness. Herein, a facile strategy 
      was introduced to synthesize the magnetic gamma-cyclodextrin polymer 
      (Fe(3)O(4)@PDA@gamma-CDP) composite and set it as a novel adsorbent with excellent 
      properties for the magnetic solid-phase extraction (MSPE) of MCs. The prepared 
      Fe(3)O(4)@PDA@gamma-CDP microspheres exhibit good aqueous dispersibility and highly 
      affinity for MCs, thus contribute to an excellent extraction performance for 
      trace MCs in water samples. Combined with HPLC-MS/MS, a handy, sensitive and 
      efficient method was developed for detection of MCs in water samples, which shows 
      good linearity (R(2) >/= 0.9992) in the range of 1.0-1000 pg mL(-1), low limits of 
      detection (0.8-2.0 pg mL(-1), S/N = 3), satisfactory repeatability with the 
      relative standard deviations (RSDs) lower than 6.2% (n = 5). At last, the 
      proposed method was successfully applied for the extraction and detection of MCs 
      in fresh water and sea water samples, which provides great potential of 
      trace-level MCs determination in lake and sea water.
