本研究描述并演示了一种通过光辐射压力分离颗粒的新的、潜在有用的方法，激光束被聚焦到含有在毛细管中同轴逆流的颗粒的溶液中，颗粒通过辐射压力被聚焦到激光束的中心线，颗粒被转向、加速、穿过束腰、现在被液体减速并漂移，此时辐射压力与现在由液体引起的力相同，从而导致颗粒分离作为尺寸的函数。
A new and potentially useful method for separation of particles by optical radiation pressure is described and demonstrated in this study, A laser beam is focused into the solution, which contains particles counterflowing coaxially in a capillary, The particle is focused into the center line of the laser beam by radiation pressure, The particle is turned around, accelerated, passed through a beam waist, decelerated by a liquid now, and drifts, at which point the radiation pressure is identical to the force induced by the liquid now, resulting in separation of particles as a function of size.
