The most complex molecular machines are found within cells.
Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.
What they didn't have were good computers, molecular machines, and designed construction materials.
Since molecular machines will arrange atoms to best advantage, a little material can go a long way.
But molecular machines directed by nanocomputers will offer physicians another choice.
The best drugs affect specific molecular machines in specific ways.
These examples show that molecular machines can reach and enter cells.
Throughout active life, molecular machines in the brain process molecules.
For a new molecular machine to function in a diffusion-based system, though, it need only be present.
This was one of the first molecular machines, a rotor.
