Nanotechnology Robots That Are As Small As Bacteria

Apr-19-09 Researchers in Zurich have built micro-robots as small as bacteria which are made to help cure disease in humans.

The tiny spiral-shaped robots, similar in look to E. coli, are called “Artificial Bacterial Flagella” (ABFs). They were invented, manufactured and enabled to swim with their moveable tails by researchers in a group at the Institute of Robotics and Intelligent Systems at ETH Zurich.

At a total length of 25 to 60 µm, They can only be observed under a microscope and perform, ironically, the opposite function of real bacteria - to help cure disease.
