Abstract
A close-packed one-dimensional array of gold nanoparticles was prepared wit h DNA as a rigid anionic polymer template. Gold nanoparticles with dense po sitive charges were prepared by modifying with dialkylammonium-disulfide. T hese cationic gold nanoparticles were adsorbed effectively on anionic DNA m olecules. Electron microscopy indicated that the particle array had a close -packed structure with a small inter-particle distance. The formation mecha nism of the close packing is discussed.
