Practical components for three-dimensional molecular nanofabrication must be simple to produce, stereopure, rigid, and adaptable. We report a family of DNA tetrahedra, less than 10 nanometers on a side, that can self-assemble in seconds with near-quantitative yield of one diastereomer. They can be connected by programmable DNA linkers. Their triangulated architecture confers structural stability; by compressing a DNA tetrahedron with an atomic force microscope, we have measured the axial… 

Rational design of DNA nanoarchitectures.

This Review is intended to provide an overview of this fascinating and rapidly growing field of research from the structural design point of view.

Fabrication of circular assemblies with DNA tetrahedrons: from static structures to a dynamic rotary motor

Inspired by rotary protein motor, a series of circular assemblies of DNA tetrahedron can serve as a stator for a rotary DNA motor to achieve the circular rotation.

Scalable, low-cost, hierarchical assembly of programmable DNA nanostructures

We demonstrate a method for the assembly of fully programmable, large molecular weight DNA complexes. The method leverages sticky-end re-use in a hierarchical fashion to reduce the cost of

DNA polyhedra with T-linkage.

Cross-over-based DNA nanomotifs are held together by T-junctions instead of commonly used sticky-end cohesion, and the resulting DNA polyhedra contain out-pointing, short DNA hairpin spikes.

Three-dimensional organization of block copolymers on "DNA-minimal" scaffolds.

A 3D-DNA construction method that assembles a minimum number of DNA strands in quantitative yield is introduced to give a scaffold with a large number of single-stranded arms, to give DNA-block copolymer cages that display increased nuclease resistance as compared to unfunctionalized DNA cages.

Toward self-assembly of phage-like nanorobot

This work demonstrates that DNA motifs can form the programmed structure without loss of the target function, and indicates that synthetic DNA molecules can provide both a packaging framework and an inner function to construct a phage-like nanorobot.

This work has shown that it is possible to construct novel DNA-based materials by combining these features in a self-assembly protocol by constructing polyhedrons, whose edges consist of double helical DNA and whose vertices correspond to the branch points.

Supramolecular Wireframe DNA Polyhedra: Assembly and Applications

This review summarizes recent advances in the rational design and programmed assembly of DNA wireframe polyhedra and applications of these polyhedral structures in templated nanomaterial assembly and in-vivo cargo delivery.



Design and self-assembly of two-dimensional DNA crystals

The design and observation of two-dimensional crystalline forms of DNA that self-assemble from synthetic DNA double-crossover molecules that create specific periodic patterns on the nanometre scale are reported.

DNA-Templated Self-Assembly of Protein Arrays and Highly Conductive Nanowires

On the basis of a two-step metallization procedure, the 4 x 4 nanoribbons acted as an excellent scaffold for the production of highly conductive, uniform-width, silver nanowires.

A 1.7-kilobase single-stranded DNA that folds into a nanoscale octahedron

The design and synthesis of a 1,669-nucleotide, single-stranded DNA molecule that is readily amplified by polymerases and that, in the presence of five 40-mer synthetic oligodeoxynucleotides, folds into an octahedron structure by a simple denaturation–renaturation procedure is reported.

Construction of a DNA-Truncated Octahedron

A covalently closed molecular complex whose double-helical edges have the connectivity of a truncated octahedron has been assembled from DNA on a solid support. This three-connected Archimedean solid

Synthesis from DNA of a molecule with the connectivity of a cube

This work reports the construction from DNA of a covalently closed cube-like molecular complex containing twelve equal-length double-helical edges arranged about eight vertices, the first construction of a closed polyhedral object from DNA.

DNA in a material world

The specific bonding of DNA base pairs provides the chemical foundation for genetics. This powerful molecular recognition system can be used in nanotechnology to direct the assembly of highly

Localized single-stranded bubble mechanism for cyclization of short double helix DNA.

It is argued that for short molecules, the formation of a few base pairs of single-stranded DNA can provide a "flexible hinge" that facilitates loop formation.

It is shown that the inherent twistability of 89- to 105-bp DNA circles exceeds theoretical expectation by up to 400-fold, which invalidate the use of classic theories of flexibility for understanding sharp DNA looping but support predictions of two recent theories.

Overstretching B-DNA: The Elastic Response of Individual Double-Stranded and Single-Stranded DNA Molecules

DsDNA molecules in aqueous buffer undergo a highly cooperative transition into a stable form with 5.8 angstroms rise per base pair, that is, 70% longer than B-form dsDNA, which may play a significant role in the energetics of DNA recombination.

Paranemic cohesion of topologically-closed DNA molecules.

The efficacy of PX cohesion is demonstrated by showing that it can result in the 1:1 binding of two triangle motifs, each containing nearly 500 nucleotides, demonstrating an alternative to binding nucleic acid molecules through sticky ends.
