FIG. 7.

(a) 3D CAD model of the third fluidic device without the top and the bottom circular polystyrene films. (b) Schematic diagram of the exploded cross-sectional view of Section A–A depicted in (a) with the top and the bottom circular polystyrene films. (c) Third 3D printed fluidic device with the integrated top and bottom 15 mm diameter 3 mil (∼75 μm) thick polystyrene films creating a circular chamber between them. (d) A blue colored food dye solution was pipetted inside the circular chamber. Channel cross-sectional dimensions were 1 mm × 1 mm and the circular chamber was 2 mm tall and 13 mm in diameter.
