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 p4mm structure.
