Background and Introduction:Background and Introduction:

• Discovery of the structure of the DNA in 1953 by Watson and Crick• Nature has been an inspiration

• DNA having unique properties, such as a nanoscale structural geometry, information encoding, self-replicating, and self-assembly, have demonstrated it as an excellent fundamental building block material for molecular nanotechnology

• DNA can be used as a bottom-up construction medium, a building block for self-assembly and as a nanostructure to construct periodic assemblies and complex nanostructures

• Using the DNA as a bottom-up construction molecule to build 3D arrays. Exploring and improving its properties to produce at a higher dimensions
