Abstract:
A fusion technology of Nanotechnology and Biotechnology.
DNA nanobiotechnology uses DNA structures and properties for constructing nanostructured material and utilizes those nanostructured materials in biological, engineering, and medical applications.
This review paper focuses on providing information about theoretical background, recent development, current state of art, innovative uses of DNA in multi-disciplinary filed, challenges and future perspective of DNA nanobiotechnology.

3. DNA Nanobiotechnology
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
