The surface density of Cryptosporidium oocysts in the microfluidic micromixers decreased from inlet to outlet. a Merged fluorescent microscopy images show the capture of oocysts in regions of the device at different distances from the inlet. (Left to right are distances of 0, 4, 8, and 12 mm from the inlet). b Average number of Cryptosporidium oocysts captured in a micromixer at 2 μl/min at different penetration lengths from inlet to outlet. The black line shows a functionalized experiment device and the red is the non-functionalized control device
