  • Microfluidic asymmetric flow field-flow fractionation device and method of using the same
    Patent number: 11946909
    Abstract: The present invention relates to an asymmetric flow field-flow fractionation device (1) configured to separate a sample (8) of particles (12) dispersed in a liquid mobile phase (11), the device including a fractionation microchannel (2) comprising a sample inlet, a sample outlet, an auxiliary microchannel (3) comprising an auxiliary outlet, a semipermeable membrane (10) separating the fractionation microchannel (2) and the auxiliary microchannel (3), said membrane being permeable to liquid and being configured to maintain the particles (12) in said fractionation microchannel (2), the fractionation microchannel (2) being superimposed on the auxiliary microchannel (3), wherein the device (1) comprises two layers (19), each layer being with a microfabricated recess (14) which thickness (t) is less than 100IJm, the membrane (10) being mechanically held in between the two layers (19), the recesses (14) respectively defining the fractionation microchannel (2) and the auxiliary microchannel (3) on each side of the m
