An IME paper "Digital microfluidics: droplet based logic gates" by Dr Levent Yobas and colleagues in Applied Physics Letters has been cited in Nature (15 February 2007) in its research highlights.
IME researchers have made microfluidic logic gates in which binary data are encoded in a fluid flow by the presence or absence of an immiscible oil droplet. The fluid is carried in microscopic channels. At a channel junction, the path a droplet takes depends on the position of droplets in the other channels, making it possible to implement logic operations. Such logic gates may place microfluidic and lab-on-a-chip devices under autonomous control.
