At the University of Michigan, professor John Hart has used nanotechnology to create images of Barack Obama, the next president of the United States. Each Obama face is made up of 150 million vertically-aligned carbon nanotubes grown at really high temperatures and imaged with a scanning electron microscope.
Carbon nanotubes are tiny hollow cylinders of carbon that are tens of thousands of times smaller than a human hair, but several times stronger and stiffer than steel. Interested in seeing more images? Click here! And, read about how they are made here! Apparently, there have been no nanoMcCains made as of yet....
