Patent ID: 11511275

Abstract:
A method for detecting, sorting, purifying and characterizing objects of interest in a liquid sample. The method comprises preparing, in a preparation module ON) of a microfluidic router system, the liquid sample for processing. Preparing comprises transporting the sample through a microfluidic channel, and forwarding the prepared sample from an outlet of the preparation module into an inlet of a routing module. Forwarding comprises coupling a microfluidic flow between the outlet and the inlet to passively buffer against or actively compensate for variations in a flow rate of the prepared sample at the outlet, and diverting the objects of interest from the microfluidic flow. Forwarding the sample comprises sensing a flow characteristic of the sample in preparation, routing module, or in flow connection, and controlling a flow control element taking the sensed characteristic into account to compensate for a variation in the flow rate by a closed-loop flow control.
