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.
The first nanomotor can be thought of as a scaled down version of a comparable microelectromechanical systems (MEMS) motor. The nanoactuator consists of a gold plate rotor, rotating about the axis of a multi-walled nanotube (MWNT). The ends of the MWNT rest on a SiO 2 layer which form the two electrodes at the contact points. Three fixed stator ...
A nanoscale plasmonic motor (sometimes called a "light mill" [1]) is a type of nanomotor, converting light energy to rotational motion at nanoscale. It is constructed from pieces of gold sheet in a gammadion shape, embedded within layers of silica .
Nano particle incorporation into micromotors has been recently studied and observed further. Specifically, gold nanoparticles have been introduced to the traditional titanium dioxide outer layer of most micromotors. [16]
This motor is driven by the flow of protons across a membrane, possibly using a similar mechanism to that found in the F o motor in ATP synthase. Molecular dynamics simulation of a synthetic molecular motor composed of three molecules in a nanopore (outer diameter 6.7 nm) at 250 K.

The prototype of a chemically driven rotary molecular motor by Kelly and co-workers. The motor by Kelly and co-workers is an elegant example of how chemical energy can be used to induce controlled, unidirectional rotational motion, a process which resembles the consumption of ATP in organisms in order to fuel numerous processes. However, it ...
The term "Brownian motor" was originally invented by Swiss theoretical physicist Peter Hänggi in 1995. [3] The Brownian motor, like the phenomenon of Brownian motion that underpinned its underlying theory, was also named after 19th century Scottish botanist Robert Brown, who, while looking through a microscope at pollen of the plant Clarkia pulchella immersed in water, famously described the ...
A future nanocar with a synthetic molecular motor has been developed by Jean-Francois Morin et al. [15] It is fitted with carborane wheels and a light-powered helicene synthetic molecular motor. Although the motor moiety displayed unidirectional rotation in solution, light-driven motion on a surface has yet to be observed.
