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]
Due to their structure and function, SNAs occupy a materials space distinct from DNA nanotechnology and DNA origami, [20] [21] (although both are important to the field of nucleic acid–guided programmable materials. [22] With DNA origami, such structures are synthesized via DNA hybridization events.
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]
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.

For example, DNA nanotechnology or cellular engineering would be classified as bionanotechnology because they involve working with biomolecules on the nanoscale. Conversely, many new medical technologies involving nanoparticles as delivery systems or as sensors would be examples of nanobiotechnology since they involve using nanotechnology to ...
DNA quaternary structure varies over time, as regions of DNA are condensed or exposed for transcription. 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.
The upper section consists of a larger, vestibule-like structure and the lower section consists of three possible recognition sites (R1, R2, R3), and is able to discriminate between each base. [21] [22] Sequencing using αHL has been developed through basic study and structural mutations, moving towards the sequencing of very long reads.
