3D 'Nanobamas' Smaller Than A Grain Of Salt

A University of Michigan professor has created 3-D portraits of the president-elect that are smaller than a grain of salt. He calls them "nanobamas." "Developments like this are an excellent way to bring the concepts of nanotechnology to a broader audience," said Hart, who made the portraits with his colleagues by working late on a Friday evening. "Also, we thought it would be fun." To create the nanobamas, the researchers converted Shepard Fairey's famous red, white and blue poster of Barack Obama to a line drawing. They shrunk it and printed it on a glass plate with a laser to create a mask. They shined ultraviolet light through the masked glass plate on to a silicon wafer to create the pattern. Then they grew the carbon nanotubes on the pattern, using a high-temperature chemical reaction. Nanobama is Hart's latest artwork too small for the naked eye to see. His complete gallery is at nanobliss.com, a site he started in 2006, inspired by the beauty in the structures he was building for his dissertation.
