Bird on a wire: A recent study by Rant and Burley showed that it is possible to transfer excited‐state energy along double‐stranded DNA by arranging fluorophore relays with base‐pair precision through Dervan‐polyamides in a cascade‐like process (see picture). The resulting assembly acts as the largest DNA‐based photonic wire yet.
