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.

Preparation and characterization of self-aggregated nanoparticles of cholesterol-modified O-carboxymethyl chitosan conjugates
TL;DR: A series of cholesterol-modified O -carboxymethyl chitosan (CCMC) conjugates with different degrees of substitution (DS) of cholesterol moiety were synthesized by the succinyl linkages and characterized by Fourier transform infrared (FTIR), proton nuclear magnetic resonance ( 1 H NMR) and elemental analysis as mentioned in this paper.

Biomimetic self-assembling peptides as scaffolds for soft tissue engineering
TL;DR: This review discusses several classes of short self-assembling sequences, explaining the principles that drive their self-assembly into structures with nanoscale ordering, and highlighting in vitro and in vivo studies that demonstrate the potential of these materials as novel soft tissue engineering scaffolds.

Direct imaging of surfactant micelles, vesicles, discs, and ripple phase structures by cryo-transmission electron microscopy
TL;DR: In this article, a model was proposed for the ripple structure and the ripple structures were shown to exist as single bilayers, which suggests that the structures observed may result from unbinding fluctuations that disrupt lamellar phases.
