World's smallest smiley faces made with 'DNA origami'
"The world's tiniest smiley faces measuring a few billionths of a metre across have been created by folding strands of DNA like origami.
"The feat was accomplished after Paul Rothemund at the California Institute of Technology simplified how to create complex structures at the nanoscale.
"Rothemund built a few DNA objects, including smiley faces, a miniature map of the U.S. and South America smaller than a typical bacterium, and a five-pointed star."
