A nanomechanical device based on the B-Z transition of DNA
Article Abstract:
Branched motifs of DNA can provide components to assemble nanoscale objects, links and arrays. It is shown than they can also act as the base for dynamic assemblies. A supramolecular device was constructed, comprising two rigid DNA double-crossover (DX) molecules. The transition between the B and Z forms of DNA are used to effect switchable motion. Fluorescence resonance energy transfer spectroscopy is used to detect relative repositioning.

Assembly of Borromean rings from DNA
Article Abstract:
The assembly of Borromean rings from single-stranded DNA could be achieved by identifying the positive and negative crossings or unit tangles then linking them into branched junctions and connecting them via the recognition-directed ligation. This construction method could be used as a guide in the formation of target topological products from other polymers.

Logical computation using algorithmic self-assembly of DNA triple-crossover molecules
Article Abstract:
The method of self-assembling DNA-based Wang tiles is demonstrated being used to carry out DNA-based computing. The system can perform four steps of a logical operation that can be used as a basis for a theoretically unbreakable cryptosystem.
