DNA nanotechnology is the design and manufacture of artificial nucleic
acid structures for technological uses. In this field, nucleic acids
such as DNA are used as non-biological engineering materials for
nanotechnology rather than as the carriers of genetic information in
living cells. Researchers in the field have created static structures
such as crystal lattices, nanotubes, polyhedra, and arbitrarily shaped
DNA origami; as well as functional structures including molecular
machines and DNA computers. The conceptual foundation for DNA
nanotechnology was first laid out in the early 1980s, and the field
began to attract widespread interest in the mid-2000s. The field is
beginning to be used as a tool to solve basic science problems in
structural biology and biophysics, such as protein structure
determination, and potential real-world applications in nanomedicine and
molecular scale electronics are under development.

Wikiquote quote of the day:
Come! Let us lay a lance in rest, And tilt at windmills under a wild
sky! For who would live so petty and unblest That dare not tilt at
something ere he die; Rather than, screened by safe majority, Preserve
his little life to little end, And never raise a rebel cry!
