In article number 1702137 , by Tohru Takarada and co‐workers, directed assembly of gold nanoroads, whose surface is densely modified with short DNA duplexes is achieved. Side‐by‐side and end‐to‐end assemblies are readily afforded due to the simultaneous stacking interaction between terminal base pairs of the DNA duplexes and repulsive steric forces induced by fraying motion of terminal‐mismatched nucleobases.
