Nanotechnology: the growing impact of shrinking computers

Nanotechnology helps make the pervasive aspect of pervasive computing possible. One obstacle to putting computers everywhere is size. You can put a desktop computer, well, on your desktop. But you can´t put it in your bloodstream (such pervasive computing applications are indeed being explored). Shrinking computers makes it possible to put them almost anywhere. To envision nanotechnology´s potential, think about building things from the molecular level up. At that level, you can build in characteristics and capabilities that aren´t readily apparent. Fueled by numerous drivers, projects from data storage to power generation to medical exploration are all putting nanotechnology to use.
