From: 3D nanomolding and fluid mixing in micromixers with micro-patterned microchannel walls
Confocal microscope images for cross-sections of a plain microchannel and 3D microchannels with b one side patterned (top side), c three sides patterned (bottom and side walls), and d four sides patterned (top, bottom and side walls) for different locations of 1, 3, 5, 10, 15, 20 and 28 mm from T-junction. Deionized water and a solution of fluorescein dye in deionized water were injected from separate inlets of the micromixer. The volumetric flow rate in the mixing microchannel was 40 μL/min. The scale bar is 20 μm
