Using feedback control and micro-fluidics to steer individual particles

We show how it is possible to combine micro-fluidics and feedback control (sense, compare, and apply corrective actuation) to steer many particles at once. The particles are steered by creating a spatially complex and time-varying fluid flow that carries all particles along their desired trajectories. We demonstrated experimental results for steering of a single yeast cell and realistic simulation results for the steering of many particles at once.
