Multi-helical DNA-silica fibers were synthesised by the self-assembly of DNA molecules with cationic organosilanes and silica sources. By electron microscopy images and circular dichroism spectra, three-level helical structures in the silica fibers have been revealed, i.e. the DNA double-helix, the secondary left-handed DNA packing and the tertiary right-handed twisting.
