Advances in nanotechnology trumps nature in designing new materials [Registered]

Nature is a master builder. Using a bottom-up approach, nature takes tiny atoms and, through chemical bonding, makes crystalline materials, like diamonds, silicon and even table salt. In all of them, the properties of the crystals depend upon the type and arrangement of atoms within the crystalline lattice. Now, a team of Northwestern University scientists has learned how to top nature by building crystalline materials from nanoparticles and DNA, the same material that defines the genetic code for all living organisms. Using nanoparticles as “atoms” and DNA as “bonds,” the scientists have learned how to create crystals with the particles…
