Elasto-inertial particle focusing and separation. a Particle focusing and separation in flow through straight microfluidic channel. 2 and 5 µm particle suspension is introduced at inlet (highlighted as yellow square). At the outlets (highlighted as red square), the 2 µm follow the flow of stream and collected at the side outlets, while the 5 µm particles migrated away from the streamline and focused at the centerline and collected through the center outlet. b Focusing profile of 5 µm particles with respect to particle Reynolds number Rp and channel length. The red, yellow and green bars are corresponding to no lateral displacement, semi displacement and complete displacement into the center channel position respectively. c Lateral position displacement of 5 µm particles at Rp = 0.008 as the function of length. d Separation of 2 and 5 µm particles at different outlets. The yield of the 5 μm particles collected at the middle outlet was 95%, and 93% for the 2 μm particles in the side outlet
