Abstract

original image

Two-ring and three-ring DNA catenane systems undergo programmed and reversible dynamic transitions between predesigned topologies by a strand-displacement mechanism. In their Communication on page 2349 ff., I. Willner and co-workers outline how the catenated DNA nanostructures hold great promise as nanomachines for the dynamic, programmed transport and arrangement of cargoes at the nanoscale.
