MICROFLUIDIC SYSTEM AND METHOD FOR PERFUSION BIOREACTOR CELL RETENTION

摘要

A microfluidic system for cell retention for a perfusion bioreactor is provided. The system comprises at least one inlet configured to receive a bioreaction mixture to be processed. At least one curvilinear microchannel is in fluid flow connection with the at least one inlet, the at least one curvilinear microchannel being adapted to isolate cells in the bioreaction mixture, based on cell size, along at least one portion of a cross-section of the at least one curvilinear microchannel. At least two outlets are in fluid flow connection with the at least one curvilinear microchannel. At least one outlet of the at least two outlets is configured to flow the isolated cells to be recycled to the perfusion bioreactor.
