Abstract
A close-packed one-dimensional array of gold nanoparticles was prepared with DNA as a rigid anionic polymer template. Gold nanoparticles with dense positive charges were prepared by modifying with dialkylammonium-disulfide. These cationic gold nanoparticles were adsorbed effectively on anionic DNA molecules. Electron microscopy indicated that the particle array had a close-packed structure with a small inter-particle distance. The formation mechanism of the close packing is discussed.
