Microfluidic chips have been in development for more than a decade now for use in, among other things, medical diagnostics. They involve micrometer-sized channels cut into plastic membranes and function as miniature laboratories. One issue that has been a challenge for microfluidics developers, however, is interfacing it with the world. It's a challenge faced in nanotechnology as well. Biomedical engineers at UC Davis think they've found an answer. And it's as simple as a device you might have on your keychain right now--a USB drive. Article
