A reconfigurable microfluidics platform for microparticle separation. (a) Schematic showing the experimental setup for observation of the spatial distributions of microparticles after passing through the tubing. (b) Photographs of (left) a cross-section of a Tygon^® tubing with an inner diameter of 190 µm and an outer diameter of 2 mm, and (right) a microchannel for measurement of the lateral distributions of the microparticles and for the collection of separated microparticles. (c) Photograph of the assembled tubing (35 cm in length) onto the grooved barrel that defines a fixed radius (1 cm) of the coiled tubing. (scale bar: 1 mm)
