US Patent 11358144 Microfluidic device for sorting out droplets

A micro-fluidic device is provided to sort out objects from a liquid stream. The device comprises a first channel comprising a first liquid and a second channel comprising a second liquid and the first liquid, and a third channel. The second channel is connected to the first channel and the channels are positioned such that a jet flow coming from the second channel can deflect objects in the first liquid into the third channel. The first liquid is a liquid which has a higher viscosity than water and the second liquid may be the same as or different from the first liquid. The micro-fluidic device is adapted for generating the jet flow in the second liquid.
