Figure 5. a) Schematic of the employed device with relevant dimensions. Particles converge gently to the glass channel, align after a certain length, and then self-order. The device in grey is a multi-contraction inlet made of polymethylmethacrylate. b) Shear viscosity as a function of the shear rate for hyaluronic acid (HA) at 1 wt% in PBS. The longest relaxation time is 37 ms. c) Higher Deborah numbers De enhances the fraction of particles ordered at s/d ≥ 3.5, where d = 20 μm is the particle diameter. Experimental snapshots at different De are also shown (same color code of the histograms). Flow is from right to left. Volumetric particle fraction is 0.6%. d) Particle ordering occurs at volumetric particle concentrations > 0.3%. Scale bar is 100 μm.
