Ratcheted electrophoresis of contact-charged particles allows for high speed transport through microfluidic channels over large distances and even against fluid flows. Using a set of predictive design heuristics, we demonstrate an extension of this microfluidic ratchet to separate conductive particles from a particle suspension.
接触带电粒子的棘轮电泳允许在微流道中高速传输，即使在有流体流动的情况下也能传输，而且传输距离很远。通过一组预测设计启发式方法，我们展示了这种微流道棘轮的扩展，用于从颗粒悬浮液中分离导电颗粒。
