Particle guiding groove

Abstract

A microfluidic device and method for allowing particles to interact with a plurality of liquids are provided. The microfluidic device includes a microfluidic channel having a bottom wall, a plurality of inlets for introducing the plurality of liquids in the microfluidic channel so as to create a plurality of parallel fluid flows in the microfluidic channel along a flow direction and an inlet for introducing dispensed particles in the microfluidic channel. The microfluidic device also has a particle guiding groove for inducing lateral movement of the particles in the microfluidic channel so that the particles are guided laterally by the particle guiding groove with respect to the average flow direction in the microchannel, so that the particles are guided through different liquids of the plurality of liquids.
