Nano-Smile
Paul Rothemund is an artist and computer scientist. Using a few DNA molecules, an atomic microscope and a computer, he can “draw” 50 billion smiley faces onto a space no larger than a drop of water.
Rothemund refers to his brew of art, biology and technology as “DNA origami,” because it is created from hundreds of DNA strands formed into nanoscale shapes and patterns. The microscopic creations are currently on display at MoMA, the Museum of Modern Art in New York City.
Rothemund says DNA origami proves that microscopic material can be formed into specific objects and someday may be used to create integrated circuits that are 10 times smaller than the circuits found in today’s computer chips. This could result in computers so small they could be fitted into clothing, wristwatches and contact lenses.
