DNA nanotechnology, specifically, is an example of bottom-up molecular self-assembly, in which molecular components spontaneously organize into stable structures; the particular form of these structures is induced by the physical and chemical properties of the components selected by the designers. [19]
The term has also been used to describe the hierarchical assembly of artificial nucleic acid building blocks used in DNA nanotechnology. [3] The quaternary structure of DNA refers to the formation of chromatin. Because the human genome is so large, DNA must be condensed into chromatin, which consists of repeating units known as nucleosomes.
Specific example applications of the standard Specific use-cases of nanoscale communication implemented using the P1906.1 definition and framework are provided. A standard mapping between a use-case, or implementation, and the standard model of the framework allows a brief summary of the information required about a use-case to understand its ...
Molecular models are useful in the design of structures for DNA nanotechnology. Here, individual DNA tiles (model at left) self-assemble into a highly ordered DNA 2D-nanogrid (AFM image at right). There are various uses of DNA molecular modeling in Genomics and Biotechnology research applications, from DNA repair to PCR and DNA nanostructures ...
Nucleic acid design is used in DNA nanotechnology to design strands which will self-assemble into a desired target structure. These include examples such as DNA machines, periodic two- and three-dimensional lattices, polyhedra, and DNA origami. [2]
Molecular self-assembly is a key concept in supramolecular chemistry. [6] [7] [8] This is because assembly of molecules in such systems is directed through non-covalent interactions (e.g., hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi-stacking interactions, and/or electrostatic) as well as electromagnetic interactions.

For example, they could be used to identify and destroy cancer cells. [ 83 ] [ 84 ] Molecular nanotechnology is a speculative subfield of nanotechnology regarding the possibility of engineering molecular assemblers , biological machines which could re-order matter at a molecular or atomic scale.
