A robust DNA mechanical device controlled by hybridization topology

  title={A robust DNA mechanical device controlled by hybridization topology},
  author={Hao Yan and Xiaoping Zhang and Zhiyong Shen and Nadrian C. Seeman},
Controlled mechanical movement in molecular-scale devices has been realized in a variety of systems—catenanes and rotaxanes, chiroptical molecular switches, molecular ratchets and DNA—by exploiting conformational changes triggered by changes in redox potential or temperature, reversible binding of small molecules or ions, or irradiation. The incorporation of such devices into arrays could in principle lead to complex structural states suitable for nanorobotic applications, provided that…

A DNA nanodevice that autonomously and processively moves along a DNA track that is in sharp contrast with cellular protein motors and manmade machines at the macroscale, both of which can continuously work without human interference.

Using gene regulation to program DNA-based molecular devices.

It is demonstrated that the operation of DNA nanomachines can be controlled in vitro using gene regulation switches, in particular those of E. coli bacteria.

Single molecule FRET analysis of the 11 discrete steps of a DNA actuator.

The results show that the DNA actuator can be effectively locked in several conformations with the help of well-designed DNA lock strands, and shows that complex DNA-based devices are inherently heterogeneous.

This review discusses DNA origami nanostructures that perform controlled translational or rotational movement triggered by predefined DNA strands, various molecular interactions and/or other external stimuli such as light, pH, temperature and electromagnetic fields.



A nanomechanical device based on the B–Z transition of DNA

This work has constructed a supramolecular device consisting of two rigid DNA ‘double-crossover’ (DX) molecules connected by 4.5 double-helical turns, using the transition between the B and Z, forms of DNA to effect switchable motion.

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.

Light-driven monodirectional molecular rotor

Attempts to fabricate mechanical devices on the molecular level have yielded analogues of rotors, gears, switches, shuttles, turnstiles and ratchets. Molecular motors, however, have not yet been

Unidirectional rotary motion in a molecular system

A molecule is described that uses chemical energy to activate and bias a thermally induced isomerization reaction, and thereby achieve unidirectional intramolecular rotary motion.

An antiparallel DNA double crossover molecule has been incorporated into one edge of a DNA triangle, incorporating the properties of branched DNA.

No braiding of Holliday junctions in positively supercoiled DNA molecules.

It is concluded that Holliday junctions do not braid at their branch points, and that the topological problem created by crossover isomerization in the parallel conformation is likely to be solved by distributing the stress over the helices that flank the branch point.

Singly and multiply configurable solid-state switching devices that are based upon electrochemically switchable molecular and supramolecular systems are discussed in terms of both the synthesis of the molecular components and the fabrication and performance of the devices.

DNA double-crossover molecules.

It is concluded that the helices between parallel double crossovers must be shielded from each other or distorted from linearity if they are to participate in recombination and be catalyzed by topoisomerases if it occurs within the cell.
