Figure 2. Fluidic devices.

(a) and (b) show a droplet device. The channels are 400 µm in diameter and the device has around 1cm² footprint and is 2.3 mm tall. In (a), there is a photograph of the device in operation, outputting droplets on the left. In (b) we show a microscope image of the channels within the device. (c) is a micrograph of a fly-over channel, where red and blue aqueous dyes cross over one another. (d) shows the 3D model of the fly-over device.
