AB  - A simple sheath flow microfluidic device is used to fabricate polymer 
      micro/nanofibers that have precisely controlled shapes and sizes. 
      Poly(methylmethacrylate) (PMMA) was used as the model polymer for these 
      experiments. The sheath-flow device uses straight diagonal and chevron-shaped 
      grooves integrated in the top and bottom walls of the flow channel to move sheath 
      fluid completely around the polymer stream. Portions of the sheath stream are 
      deflected in such a way as to define the cross-sectional shape of the polymer 
      core. The flow-rate ratio between the sheath and core solution determines the 
      fiber diameter. Round PMMA fibers with a diameter as small as 300 nm and 
      flattened fibers with a submicron thickness are demonstrated.
