"Jim Tour and colleagues at Rice University in Houston, US, built a chassis and wheels for a nano-car from organic molecules...

The nano-car's molecular motor contains a pair of bonded carbon molecules that rotate in one direction if illuminated by a specific wavelength of light."

"..researchers at the Free University of Berlin in Germany and the Center for Material Elaboration & Structural Studies in Toulouse, France"...

..using an electron microscope, have produced images of the nanowheels in action...

"..hundreds of these "nanowheels" were sprayed onto a sheet of copper. The researchers then used the tip of a scanning tunnelling electron microscope (STEM) to push individual molecules across a copper surface."

As soon as a Nano-movie of the light powered Nanowheels or a Nanocar become available I will load it here at SCIENCE BLOGS, and at the fast breaking site MICHAEL HOLLOWAY'S FilterBlogs.
