A team of U.S. and European researchers has developed an elegant method for producing individual, continuous chains of palladium ions. The process is based on self-organized assembly of a special palladium complex and single-stranded DNA molecules (which are becoming an important tool for nanoscience and nanotechnology). The incorporation of metals in DNA structures can give them properties such as conductivity, catalytic activity, magnetism, and photoactivity. But organizing metal ions in DNA molecules is not easy. So, the researchers used a specially constructed palladium complex that can form base pairs with natural adenine bases in a strand of DNA.
