Back Cover: Engineering Micrometer‐Sized DNA Tracks for High‐Speed DNA Synthesis and Biosensing (Angew. Chem. Int. Ed. 51/2020)

A DNA assembly , namely a micrometer‐sized DNA track, was engineered by M. Liu, Y. Li, and co‐workers in their Communication on page 22947. The DNA track is made of a long‐chain DNA with a primer‐binding domain at its 3′ end and circa 1000 repeating sequence units at its 5′ end each carrying a DNA anchor, and can serve as an efficient template for in vitro DNA synthesis by DNA polymerases.
