摘要
(Figure Presented) Templated metalation of DNA junctions allows incorporation of a range of transition metals into DNA assemblies. The resulting highly stable metal-DNA junctions can be assembled into dynamic multinuclear structures, with metal centers as their corners and DNA single strands as their sides. Ready and reversible structural switching of these assemblies with external agents (see picture) allows for control of geometry and metal-metal distances. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
