a A rectangular cross-sectional multiline separation structure166. b Spiral VEM channel to suggest that the Dean drag force and viscoelastic forces together alter the trajectory in a spiral channel167. c Particles traveling in between the sample and sheath flow169. d Co-flow of viscoelastic and Newtonian media devices, which achieves an over 90% separation efficiency and purity of 1 µm Staphylococcus aureus and 2–3 µm platelets170
