Zipped together : The title system was synthesized by using a quaternary ammonium silane as a DNA‐condensing agent and a co‐condenser with the silica source. The small interaxial separation in electrostatic DNA–DNA “zippers” and silica walls formed between diagonally positioned DNA strands are optimal for formation of the p 4 mm structure.
