DNA origami is the nanoscale folding of DNA to create arbitrary two and three dimensional shapes at the nanoscale. The specificity of the interactions between complementary base pairs make DNA a useful construction material through design of its base sequences. Developed by Paul Rothemund at the California Institute of Technology, the process involves the folding of a long single strand of viral DNA aided by multiple smaller "staple" strands. These shorter strands bind the longer in various places, resulting in various shapes including a smiley face and a coarse map of China and the Americas, along with many three dimensional structures such as cubes.
