One of the most fascinating branches of nanotechnology involves the sculpting of DNA into tiny shapes in a process known as DNA origami. The field was pioneered in 2006 by Paul Rothemund of Caltech. Now, researchers at Arizona State University's Biodesign Institute have taken Rothemund's work and given it more shape, adding contours that more accurately mimic shapes commonly found in nature. These shapes could house therapeutics and selectively deliver them on the molecular or cellular level. Release | Video
