Nanomachines

Implants and tiny machines could eventually help treat disease or monitor activity, but communication is tricky. Now scientists at EPFL have developed a system whereby devices can communicate by releasing molecules into a patient’s bloodstream.

Researchers at Empa and EPFL have created one of the smallest motors ever made. It’s composed of just 16 atoms, and at that tiny size it seems to function right on the boundary between classical physics and the spooky quantum realm.

Particularly promising against superbugs are mechanical solutions like Rice University’s “nanodrills,” which bore into cell walls. Now, the team has shown that the devices work against larger organisms like worms and water fleas.
