Schematic illustration of elasto-inertial microfluidics based particle migration and separation in flow through straight channel. A mixture of small (red) and large (blue) particles entered the channel along the sidewalls and non-Newtonian solution is used as sheath at the center. The net result of elastic (Fe) and inertial forces (shear-induced lift force, FLS, and wall-induced lift force, FLW) affect the large particles such that they laterally migrate to three dimensional single stream in the middle of channel while the small particles keep flowing along the wall and can be separated
