A team led by Charles Lieber, a professor of chemistry at Harvard, and Shamik Das, lead engineer in MITRE's nanosystems group, has designed and built a reprogrammable circuit out of nanowire transistors. Several tiles wired together would make the first scalable nanowire computer, says Lieber. Such a device could run inside microscopic, implantable biosensors, and ultra-low-power environmental or structural sensors, say the researchers.
