TLDR
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.

Generation of 2D organic microsheets from protonated melamine derivatives: suppression of the self assembly of a particular dimension by introduction of alkyl chains
TL;DR: In this article, the assembly and disassembly of 2D organic microsheets can be reversibly controlled by alternating addition of acid and base, and even the aspect ratio of the rectangular microsheet can be further modulated by different amounts of acid.

TL;DR: It is demonstrated that diphenylalanine peptide nanotubes are indeed electrically switchable if annealed at a temperature of about 150 °C and the new orthorhombic antipolar structure that appears after annealing allows for the existence of a radial polarization component, which is directly probed by piezoresponse force microscopy (PFM) measurements.

Heat‐Induced Morphological Transformation of Supramolecular Nanostructures by Retro‐Diels–Alder Reaction
TL;DR: This work shows that a morphological transformation from 2D nanosheets to a network of 1D nanofibers is triggered by heating, which induces molecular conversion of a bolaamphiphile to a hydrogelator by means of a retro-Diels-Alder reaction, thereby producing a new heat-set supramolecular hydrogels.

Chaotropic‐Anion‐Induced Supramolecular Self‐Assembly of Ionic Polymeric Micelles
TL;DR: A surprising chaotropic-anion-induced micellization of cationic ammonium-containing block copolymers is reported, for which only a three-fold increase in ClO4(-) concentration was necessary for micelle formation, similar to the previously reported ultra-pH-responsive behavior.
