摘要： A system for orienting particles in a microfluidic system includes one or more radiation pressure sources arranged to expose particles to radiation pressure to cause the particles to adopt a particular orientation in the fluid. A system for sorting particles in a microfluidic system includes a detection stage arranged to detect at least one difference or discriminate between particles in the fluid flow past the detection stage, and one or more radiation pressure sources past which the particles move sequentially and a controller arranged to switch radiation energy to cause a change in direction of movement of selected particles in the fluid flow to sort the particles. The particles may be biological particles such as spermatazoa. The radiation pressure may be optical pressure and may be from one or more waveguides which may extend across a channel of the microfluidic system.
