The world's smallest wedding rings

Abstract:
Creating artificial structures from DNA is the objective of DNA nanotechnology. This new discipline, which combines biology, physics, chemistry and material science makes use of the ability of the natural DNA-strains' capacity for self assembly. Smileys or small boxes, measuring only 10s of nanometers (10 one-billionths of a meter) were created from DNA in a drop of water. Prof Alexander Heckel and his doctoral student Thorsten Schmidt from the "Cluster of Excellence for Macromolecular Complexes" at Goethe University were able to create two rings of DNA only 18 nanometers in size, and to interlock them like two links in a chain. Such a structure is called catenan, a term derived from the Latin word catena (chain). Schmidt, who got married during the time he was working on the nano-rings, believes that they are probably the world's smallest wedding rings.
