ScienceDaily (Apr. 12, 2011) DNA nanotechnology makes use of the ability of natural DNA strains' capacity for self asssembly. Prof. Alexander Heckel and his doctoral student Thorsten Schmidt of 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.
