DNA-based nanotechnology has been around for more than 30 years, but it really took off in 2006, when DNA origami was featured on the cover of Nature. This form of origami, the folding of DNA into 2D and 3D shapes, was more of an art form back then, but scientists are now using the approach to construct nanoscale robots.

The basic principle of DNA origami is that a long, single-stranded DNA molecule will fold into a predefined shape through the …read more
