AB  - Poly(dimethylsiloxane) (PDMS) microfluidic channels modified by 
      citrate-stabilized gold nanoparticles after coating a layer of linear 
      polyethylenimine (LPEI) were successfully used to separate dopamine and 
      epinephrine, which were difficult to be separated from baseline in native and 
      hybrid PDMS microchannels. In-channel amperometric detection with a single carbon 
      fibre cylindrical electrode was employed. Experimental parameters of separation 
      and detection processes were optimized in detail. The analytes were well 
      separated within 100 s in a 3.7 cm long separation channel at a separation 
      voltage of +800 V using a 30 mM phosphate buffer solution (PBS, pH 7.0). Linear 
      responses of them were obtained both from 25 to 600 microM with detection limits 
      of 2 microM for dopamine and 5 microM for epinephrine, respectively. The modified 
      PDMS channels have a long-term stability and an excellent reproducibility within 
      2 weeks.
