Synthesis of Monodisperse Microparticles from Non‐Newtonian Polymer Solutions with Microfluidic Devices

Polymer solutions are useful precursors to synthesize microparticles with microfluidic devices, but most polymer solutions are incompatible with microfluidic emulsification due to their non-Newtonian flow characteristics. A technique is presented to form monodisperse particles from such solutions by surrounding them with a chaperoning Newtonian fluid and forcing both to pinch into preparticle drops.
