| Research Abstract |
In this study, we tried to establish the technique for construction of integrated circuit using metalic nano-object/DNA conjugates by self-organization of the DNAs. We prepared divalent DNA/gold nanoparticle(AuNP) conjugates attaching two DNA strands at diametrically opposed positions. We prepared one- and two-dimensional AuNP arrays with regulated distances and geometries using the divalent DNA/AuNP conjugates. To obtain AuNP arrays with high linearity, we designed AuNP array systems in juxtaposition using a T-motif and a double crossover (DX)-motif. More precise arrangements and control of distance between AuNPs can be achieved by using the T-motif and DX-motif. Moreover, tetragonal lattice-like 2D structure was observed by using Holliday junction forming conjugates.
