| Research Abstract |
In this study, we demonstrated that aggregation structures of gold nanoparticles can be controlledwithliquid crystal(LC) molecules. AFM topographical images of gold nanoparticles on a polyimide alignment layer showed that the nanoparticles were arranged in lines, and those one-dimensional aggregations were oriented toward the rubbing direction. We consider that due to the surface anchoring effect the LC molecules are aligned to one direction on the polyimide alignment layer and this induced the one-directional alignments of the liner aggregations of nanoparticles.
