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.

Nanohedra: Using symmetry to design self assembling protein cages, layers, crystals, and filaments
TL;DR: A general strategy is described for designing proteins that self assemble into large symmetrical nanomaterials, including molecular cages, filaments, layers, and porous materials, some of which share similar features with natural biological assemblies.

Lithography and Other Patterning Techniques for Future Electronics
TL;DR: In this paper, the authors focus on the benefits of using ICs at the 22-nm node and beyond, and no shortage of ideas on how to accomplish this, although it is not clear that optics will be the most economical in this range; extreme ultraviolet is still the official front runner, and electron beam lithography, which has demonstrated minimum features less than 10 nm wide, continues to be developed both for mask making and for directly writing on the wafer (also known as ldquomaskless lithographyrdquo).

Common features of protein unfolding and dissolution of hydrophobic compounds
TL;DR: A general representation of protein stability is given by the heat capacity change and the temperature, and a hydrophobic and a nonhydrophobic contribution are described.

Exploitation of the hydrogen bond: recent developments in the context of crystal engineering
TL;DR: A review of recent developments in the field with particular emphasis on how symmetry and function at the molecular level can be used to control solid-state architecture is provided in this paper, where hydrogen bonding represents perhaps the best understood non-covalent force.
