Medical Micro-robots Made As Small As Bacteria.
For the first time, ETH Zurich researchers have built micro-robots as small as bacteria.
They look like spirals with tiny heads, and screw through the liquid like miniature corkscrews. When moving, they resemble rather ungainly bacteria with long whip-like tails. They can only be observed under a microscope because, at a total length of 25 to 60 µm, they are almost as small as natural flagellated bacteria. Most are between 5 and 15 µm long, a few are more than 20 µm.
