From MSNBC:
A computer scientist has developed a method to weave stringy DNA molecules into nanometer-scale, two-dimensional patterns ranging from smiley faces to a map of the Americas. Experts say the “DNA origami” procedure laid out by Paul Rothemund of the California Institute of Technology could be adapted to create nano-computers, new drug delivery systems or even molecular-scale chemical factories. “We are arriving at a new frontier in our pursuit of ever-smaller structures,” Lloyd Smith, a chemist at the University of Wisconsin at Madison, said in Thursday’s issue of the journal Nature, where Rothemund’s research was published.
