Fig. 3. Macroscopic template-assisted self-assembly using mechanical instabilities. (A) Schematic template-assisted self-assembly process by dip coating the wrinkled templates in a highly concentrated gold nanorod solution. (B) AFM image of the self-assembled array of gold nanorods in the wrinkle template. (C) Schematic transfer process using wet-contact printing and subsequent lift-off of the emptied template. (D) SEM image of the assembled structures transferred to a smooth gold film and photographs of the macroscopic substrate in reflection and transmission (upper and lower inset, respectively).
