Miniature architectural forms -- some no larger than viruses -- have been constructed through a revolutionary technique known as DNA origami. Now, Hao Yan, Yan Liu and their colleagues at Arizona State University's Biodesign Institute have expanded the capability of this method to construct arbitrary, two and three-dimensional shapes, mimicking those commonly found in nature.

Such diminutive forms may ultimately find their way into a wide array of devices, from ultra-tiny computing components to nanomedical sentries used to target and destroy aberrant cells or deliver therapeutics at the cellular or even molecular level.
