Nano Obama=Nanobama

The picture shown above contains microscopic faces of Barack Obama made using nanotechnology, and imaged using a scanning electron microscope. Each face consists of millions of vertically-aligned carbon nanotubes, grown by a high temperature chemical reaction.

Using carbon nanotubes as his medium, mechanical engineering professor John Hart has created the world’s tiniest portrait of President-Elect Barack Obama. There are about 150 million nanotubes in each NanObama - roughly one for each person who voted in the presidential election.

Carbon nanotubes and other nanostructures are building blocks for many important technological advances, including high-performance solar cells and batteries, new methods of diagnosing and treating disease, next-generation computer processors and memory, and lightweight composite materials.
