Abstract

original image

A helical turn full of metal ions! The metal–salen base-pair concept allows the incorporation of up to 10 transition-metal ions into double strands of DNA (see picture; Mn gray spheres, C gray, N blue, P orange, O red). The crosslinking provided by the metal–salen complexes conveys a high stability to the self-assembled systems.
