Obama's likeness used to promote nanotechnology

President-elect Barack Obama is larger than life these days. Except, that is, at the University of Michigan, where he has become remarkably small. A team of researchers has created carbon nanotube images of Obama whose details can only be seen with optical and electron microscopes. "I really didn't mean it in a political way," said John Hart, assistant professor in mechanical engineering and leader of the research team at Michigan. "It was really for fun. It was a basic demonstration of what we can do with nanotubes." Hart said he hopes the interest in "nanobama" gives the public a better understanding of nanotechnology research and its applications.
