using 2D templates consisting of surfactant systems at the air/water interface is demonstrated by M. Brust and T. Bjørnholm and co-workers. The morphology of the resulting nanostructures can be partially controlled by adjusting parameters such as the molecular structure of the surfactant, the chemical properties of the assembly units, and the surface pressure.
