Engineers develop first method for controlling nanomotors

In a breakthrough for nanotechnology, engineers at The University of Texas at Austin have developed the first method for selecting and switching the mechanical motion of nanomotors among multiple modes with simple visible ...

Scientists introduce new way to mimic 'machine of machines'

Like small-scale Legos clicking into place, nature autonomously puts together microscopic building blocks. Living systems are biochemical machines that excel at building and moving their parts. Just as machines need energy ...

Tiny DNA 'legs' walk with record fuel efficiency

(Phys.org)—For the first time, researchers have demonstrated a DNA nanomotor that can "walk" along a track with sustainable motion. The nanomotor also has the highest fuel efficiency for any type of walking nanomotor, or ...

Chemically driven micro- and nanomotors

At least since the movie "The Fantastic Voyage" in 1966, in which a submarine is shrunk down and injected into the blood stream of a human, people have been toying with the idea of sending tiny "micromachines" and "nanorobots" ...

Engineers build world's smallest, fastest nanomotor

Researchers at the Cockrell School of Engineering at The University of Texas at Austin have built the smallest, fastest and longest-running tiny synthetic motor to date. The team's nanomotor is an important step toward developing ...

Nanomotor

A nanomotor is a molecular device capable of converting energy into movement. It can typically generate forces on the order of piconewtons.

A proposed branch of research is the integration of molecular motor proteins found in living cells into molecular motors implanted in artificial devices. Such a motor protein would be able to move a "cargo" within that device, via protein dynamics, similarly to how kinesin moves various molecules along tracks of microtubules inside cells.

Starting and stopping the movement of such motor proteins would involve caging the ATP in molecular structures sensitive to UV light. Pulses of UV illumination would thus provide pulses of movement. Nanomotors have also been made using synthetic materials and chemical methods.
