Abstract:
The development of programmable growth patterns with predictable self-assembly at the molecular scale is a key target of nanotechnology. We present here a DNA nanostructure, Scaffold Cross Tile consisting of 4×4 arm junction with a square aspect ratio. The 8 ssDNA oligonucleotides are designed in a way that the adjacent strands with sticky ends association can produce continuous arms both in X and Y direction representing tile-based origami. The self-assembled scaffold cross tiles result in two-dimensional nanogrids with periodic square cavities. The Scaffold cross tile lattice structure is not only assembled in free solution but also grown on mica substrate. A mica-assisted crystal growth phase diagram is analyzed by atomic force microscopic images with rational growth analysis by annealing SXT in different concentrations. These 4x4 scaffold nanogrids may prove to be useful as a nanoscale contact mask for transferring metallic and ferromagnetic square patterns onto a silicon substrate through vapor deposition.
