generation of portable devices
Wouldn't it be handy if everything we needed to build the next generation of portable devices and robots were available on a microchip? You could just plug in a navigation system, a radar sensor, cryogenic cooling system, or even a miniature power unit. For laboratory applications, there would be micro versions of everything from mass spectrometers to magnetic sensors. The Defence Advanced Research Projects Agency (Darpa), the Pentagon's extreme science wing, aims to provide all this, and more, in handy "matchbook size" electronic packages.
"Darpa was instrumental in helping support much of the initial development of lab-on-a-chip in the early 90s," says Jon Cooper, Wolfson chair of bioengineering at the University of Glasgow. "The technologies enabled a number of US startup companies to develop miniaturised chips for faster biological analysis, giving them the necessary long-term support to grow."
