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.

On the decidability of self-assembly of infinite ribbons
TL;DR: It is proved that it is undecidable whether an arbitrary finite set of tiles with glues can be used to assemble an infinite ribbon, a non-self-crossing sequence of tiles on the plane, in which successive tiles are adjacent along an edge, and abutting edges of consecutive tiles have matching glues.

A novel single precursor-based biodegradable hydrogel with enhanced mechanical properties
TL;DR: A mechanically tough biodegradable hydrogel is developed from a single precursor comprising poly(ethylene glycol) and oligo(trimethylene carbonate), where both the crosslink density and swelling properties of the polymer network are independently controlled through c and hydrophilic-hydrophobic balance.

Macromolecular self‐organized assemblies
TL;DR: In this article, the use of surface textures to induce a form of graphoepitaxy in colloidal particle packing is discussed, and a wide variety of geometrical packing arrangements can be produced by controlling methods used to coat colloidal particles into a substrate.
