Scientists have harnessed DNA's self-assembling abilities to build nanostructures in a variety of shapes such as spheres and bottles. A team of scientists at Arizona State University showed that they can build nanostructures with high curvature from DNA.

Using this technique, it may be possible to build nanoscale machines and electronic devices, including computer chips with smaller features.

DNA is naturally self-assembling, and uses this capacity to combine and reassemble parental genes to create a new genetic map for offspring. The Arizona State researchers induced the DNA to build various nanostructures, including 2-D shapes and 3-D spherical and ellipsoidal shells and nanobottles.
