N2 - 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 flow, and drifts, at which point the radiation pressure is identical to the force induced by the liquid flow, resulting in separation of particles as a function of size.
