About the cover

October 2015 Volume 10 No 10

The ability to reliably handle individual polymer chains could lead to the fabrication of miniaturized electronic and optical wires. To this end, Kurt Gothelf, Mingdong Dong and colleagues have now developed a method to control the shape individual polymer molecules adopt. They synthesized a polymer with short single-stranded DNA extending from the backbone enabling the polymer to self-assemble into predesigned routings using the complementary DNA strands extending from 2- and 3D DNA origami structures. The artist’s impression on the cover shows the DNA-functionalized polymer assembling on a U-shaped track on a rectangular DNA origami template.
