'Nanobot?' Maybe not, but cool, anyway

The Jerusalem Post briefly features the work of Avi Schroeder, an Israeli scientist working at the Massachusetts Institute of Technology, and his "cancer fighting robots." Actually, "robot" might be a rather ambitious word for the technology, but it is ingenious nonetheless. It is a swallowable capsule that releases cancer-fighting proteins when triggered by irradiated light. It is, however, just 170 nanometers in diameter. Some nano purists say that to be considered true "nanotechnology," it needs to be 100 nanometers or less, but we'll stretch that definition just a bit, too, and call Schroeder's invention a "nanobot" just because it sounds cool.
