Experiment Shows Molecules Can Walk, but Can They Dance?
Abstract:
In efforts to create motors and other machines on the scale of molecules — machines that can act as tiny assembly lines to make novel compounds — the devices have to walk before they can run. And when it comes to walking, molecular machines have to be able to do so on their own, in the proper direction. Most molecular walkers need some help, in the form of chemicals to keep them going, and they tend to wander.
Researchers at New York University and Harvard have created a two-legged walker, made from a strand of DNA, that solves both of those problems — it walks on its own in one direction along a track, also made of DNA strands.
