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.Abstract:
Molecular self-assembly is the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds. Molecular self-assembly is ubiquitous in biological systems and underlies the formation of a wide variety of complex biological structures. Understanding self-assembly and the associated noncovalent interactions that connect complementary interacting molecular surfaces in biological aggregates is a central concern in structural biochemistry. Self-assembly is also emerging as a new strategy in chemical synthesis, with the potential of generating nonbiological structures with dimensions of 1 to 10(2) nanometers (with molecular weights of 10(4) to 10(10) daltons). Structures in the upper part of this range of sizes are presently inaccessible through chemical synthesis, and the ability to prepare them 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.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.

Fabrication of novel biomaterials through molecular self-assembly.
TL;DR: Two complementary strategies can be used in the fabrication of molecular biomaterials as discussed by the authors : chemical complementarity and structural compatibility, both of which confer the weak and noncovalent interactions that bind building blocks together during self-assembly.

TL;DR: It is found that 4,4'-bipyridines functionalized in their 3,3'-positions with Fréchet dendrons of 0th to 3rd generation self-assemble with (dppp)M(II) triflates into metallo-supramolecular squares, causing the formation of "tower-like" aggregates and multi-layer formation.

TL;DR: It is shown here that the flexible polyamine receptor L discriminates among H2mal/H2fum diastereomers, succinic acid (H2suc), and three isomers of benzenedicarboxylic acid, by adapting its conformation and finally forming different solid hydrogenbonded (HB) frameworks.

One-Dimensional Confinement of Organic Molecules via Selective Adsorption on CaF1 versus CaF2
TL;DR: In this paper, the authors integrated one-dimensional organic structures into semiconductor/insulator nanostructures by controlled self-assembly, and demonstrated the selectivity in terms of a mechanism where the HOMO and LUMO of the molecule interact with the valence band and conduction band of CaF1 and CaF2.
