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

Hierarchical self-assembly of metal nanostructures on diblock copolymer scaffolds
Ward Lopes,Heinrich M. Jaeger +1 more
TL;DR: It is found that, in contrast to the usual requirement of near-equilibrium conditions for ordering, the metal arranged on the copolymer scaffold produces the most highly ordered configurations when the system is far from equilibrium.

Self-Assembled Aggregates of Rod-Coil Block Copolymers and Their Solubilization and Encapsulation of Fullerenes
Samson A. Jenekhe,X. Linda Chen +1 more
TL;DR: Amphiphilic poly(phenylquinoline)-block-polystyrene rod-coil diblock copolymers were observed to self-organize into robust, micrometer-scale, spherical, vesicular, cylindrical, and lamellar aggregates from solution, but their size scale decreased with a decreasing fraction of the rigid-rod block.

TL;DR: In this paper, the self assembly of peptide hydrogelators that carry aromatic substituents can be modeled by a novel nanocylindrical architecture, which is consistent with the structures observed in TEM and the data obtained by a variety of spectroscopic techniques.

Molecular self-assembly of surfactant-like peptides to form nanotubes and nanovesicles
TL;DR: Several surfactant-like peptides undergo self-assembly to form nanotubes and nanovesicles having an average diameter of 30–50 nm with a helical twist, with significant implications in the design of nonlipid biological surfactants and the understanding of the complexity and dynamics of the self- assembly processes.

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.
