Cover Picture: DNA-Templated Silver Nanorings (Adv. Mater. 23/2005)

17_23/2005The cover shows that toroidal condensates of duplex DNA can be used as templates for facile preparation of monodisperse nanorings of noble metals. In the work by Zinchenko and co-workers, reported on p. 2820, conformational transition of long DNA chains from elongated coils into compact toroidal condensates changes the manner of reduced silver deposition, from DNA chain metallization with nanoparticles to the formation of silver rings. A one-pot, three-step, simple preparation method leads to formation of well-defined monodisperse silver nanorings (100 nm in diameter) dispersed in water.
