Design and self-assembly of two-dimensional DNA crystals
TLDR
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.Abstract:
Molecular self-assembly presents a `bottom-up' approach to the fabrication of objects specified with nanometre precision. DNA
molecular structures and intermolecular interactions are particularly
amenable to the design and synthesis of complex molecular objects. We
report the design and observation of two-dimensional crystalline forms
of DNA that self-assemble from synthetic DNA double-crossover
molecules. Intermolecular interactions between the structural units are
programmed by the design of `sticky ends' that associate according to
Watson-Crick complementarity, enabling us to create specific periodic
patterns on the nanometre scale. The patterned crystals have been
visualized by atomic force microscopy.read more

Folding DNA to create nanoscale shapes and patterns
TL;DR: This work describes a simple method for folding long, single-stranded DNA molecules into arbitrary two-dimensional shapes, which can be programmed to bear complex patterns such as words and images on their surfaces.
Molecular self-assembly and nanochemistry: A chemical strategy for the synthesis of nanostructures
TL;DR: In this article, self-assembly is defined as the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds.

DNA in a material world
TL;DR: The specific bonding of DNA base pairs provides the chemical foundation for genetics and this powerful molecular recognition system can be used in nanotechnology to direct the assembly of highly structured materials with specific nanoscale features, as well as in DNA computation to process complex information.

Atomic force microscope
TL;DR: The atomic force microscope as mentioned in this paper is a combination of the principles of the scanning tunneling microscope and the stylus profilometer, which was proposed as a method to measure forces as small as 10-18 N. As one application for this concept, they introduce a new type of microscope capable of investigating surfaces of insulators on an atomic scale.

Molecular self-assembly and nanochemistry: a chemical strategy for the synthesis of nanostructures.
TL;DR: The ability to prepare structures in the upper part of this range of sizes would open a route to structures comparable in size (and perhaps complementary in function) to those that can be prepared by microlithography and other techniques of microfabrication.
