  author={Chengde Mao and Weiqiong Sun and Zhiyong Shen and Nadrian C. Seeman},
The assembly of synthetic, controllable molecular mechanical systems is one of the goals of nanotechnology. Protein-based molecular machines, often driven by an energy source such as ATP, are abundant in biology,. It has been shown previously that branched motifs of DNA can provide components for the assembly of nanoscale objects, links and arrays. Here we show that such structures can also provide the basis for dynamic assemblies: switchable molecular machines. We have constructed a… 

A molecular machine made and powered by DNA

The construction of a new class of active nanostructure: a machine in which DNA is used not only as a structural material but also as a fuel.

A DNA-fuelled molecular machine made of DNA

The construction of a DNA machine in which the DNA is used not only as a structural material, but also as ‘fuel’; each cycle produces a duplex DNA waste product.

A robust DNA mechanical device controlled by hybridization topology

It is shown that DNA strands control and fuel the device cycle by inducing the interconversion between two robust topological motifs, paranemic crossover (PX) DNA and its topoisomer JX2 DNA, in which one strand end is rotated relative to the other by 180°.

Two Dimensions and Two States in DNA Nanotechnology

Although individual branched junctions are unsuitable for use as crystalline components, parallelograms of four 4-arm junction molecules are sufficiently rigid that they can be used to produce 2D arrays, and these arrays contain cavities whose dimensions are readily tuned by changing the edges of their parallelogram components.

A DNA-fuelled molecular machine made of DNA

The construction of a DNA machine in which the DNA is used not only as a structural material, but also as `fuel', is reported, in which double-stranded DNA has a persistence length of the order of 100 base pairs.

Nucleic Acid Nanostructures: Bottom-Up Control of Geometry on the Nanoscale.

A DNA-based nanomechanical device with three robust states

This work describes a system in which three different structurally robust end states can be obtained, all resulting from the addition of different set strands to a single floppy intermediate, an extension of the PX-JX2 DNA device.

This review focuses on two noncanonical classes of DNA helices: G-quadruplexes and the i-motif, which have been utilized toward some remarkable constructions and applications.

Direct and real-time observation of rotary movement of a DNA nanomechanical device.

Two types of physical models have been developed for treating DNA molecules whose topology is of interest, which present a low-resolution construct of DNA that retains helix axes, strand individuality and the distinguishability of the major and minor grooves.

Determination of DNA helical handedness by fluorescence resonance energy transfer.

The method has been applied to a family of oligonucleotides forming hairpin duplexes containing an antiparallel-stranded (aps) d(m5C.G)m and concluded that psAT-DNA has a helical rise and twist close to that of B-DNA.
