DNA nanotechnology makes use of the ability of natural DNA strains' capacity for self asssembly. Researchers in Germany were able to create two rings of DNA only 18 nanometers in size, and to interlock them like two links in a chain. One of the researchers, who got married during the time he was working on the nano-rings, believes that they are probably the world's smallest wedding rings.
