Last month brought a potentially path-breaking announcement from an international team of researchers. The team has developed a self-powered blood-analysis chip (see Ivan Dimov's photograph on the left), which can process blood without the assistance of external tubing and other components. This means that it could be used to detect diseases like HIV and TB within minutes, revolutionizing the way these diseases are tested for.
The implications are exciting: The portable nature of the device would make it easy for field workers to it use for diagnosis, and the fact that it is made of plastic components means it could be manufactured in bulk at comparatively low prices.
