聚合物溶液是利用微流控装置合成微粒子的有效前驱体，但由于其非牛顿流动特性，大多数聚合物溶液与微流控乳化不相容。提出了一种从这种溶液中形成单分散粒子的技术，方法是用陪伴的牛顿流体将它们包围，并迫使它们挤压成前粒子液滴。
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.
