A periodic structure of gold nanoparticles (AuNPs) is formed by reducing a solution of gold chloride using novel plasma techniques, where a spatio-periodically generated plasma is transcribed to the AuNP structure formed on the ionic liquid (IL) surface under the strong magnetic field. In addition, it is found that a ring-shaped AuNP structure is formed corresponding to the shape of a ring electrode inserted into the plasma, where the AuNPs are synthesized at the position without plasma irradiation due to the shielding by the ring electrode. On the other hand, the periodic structure of the AuNPs are synthesized on the carbon nanotubes (CNTs) working as a template, where the controlled ion irradiation to the IL including functional groups can realize the distancecontrolled synthesis of the AuNPs by dissociation of the IL and the functionalization of the CNTs by the dissociated carboxyl and amino groups. Furthermore, DNA is used as the functional group which connects the AuNPs to the CNTs. The mono-dispersed and high-density AuNPs are synthesized on the CNTs in the same way as the carboxyl and amino groups.
