Increasingly, origami (the Japanese art of paper folding) is becoming less of an artistic concern and more of a scientific one. The California Institute of Technology made special news in 2006 about a way to weave DNA strands into any two-dimensional shape or figure. Caltech’s Paul Rothemund called it “DNA origami” but that was just the start of it. Image credits: Nikoline Arns. Imagine strands of DNA folded back and forth, forming a scaffold that fills the outline of a desired shape. Then, imagine more DNA strands specially designed to bind to that scaffold. Rothemund, the strand-weaver, explained why this was useful. Scientists would find it easy to create and study any complex nanostructures they might want. Quoted in a 2006 press release, in he said he came up with a half a dozen shapes, including square, triangle, five-pointed star, and smiley face.
