Recent studies have shown that supramol. Furthermore, the assembly pathway can influence the shape, internal structure, and dimension of nanostructures and thereby affect their bioactivity. The authors discuss methods to map the energy landscape of a PA structure as a function of thermal energy and ionic strength and vary these parameters to convert between kinetically trapped and thermodynamically favorable states.
The authors also demonstrate that the pathway-dependent morphol. The dynamics assocd. For example, by conjugating radical electron spin labels to PAs, ESR spectroscopy can be used to study the rotational diffusion rates within the fiber, showing a liq. PAs can also be labeled with fluorescent dyes, allowing the use of super-resoln. For a weak hydrogen-bonding PA, individual PA mols.

PAs are a promising platform for designing advanced hybrid materials. The authors discuss a covalent polymer with a rigid arom. PA structure with identical chem. The covalent polymn. These novel hybrid structures have potential in self-repairing materials and as reusable scaffolds for delivery of drugs or other chems.
Finally, the authors highlight recent biomedical applications of PAs and related structures, ranging from bone regeneration to decreasing blood loss during internal bleeding. An alternative method to synthesize intermediate nanoscopic size steroid nanotubes is presented which used a simple aq.

The salts of bile acids bile salts self-assemble in aq. The micellization is not only driven by the hydrophobic effect, but also hydrogen binding. Moreover, instead of a small, hydrophilic head and a flexible, hydrophobic tail, bile salts are rigid, almost flat mols. This results in a complex self-assembly behavior with very distinct aggregate properties. Some characteristics resemble the behavior of classical amphiphiles, while others are very different and reminiscent of other classes of mols.
Reviewed are the peculiar properties of bile salt aggregates, concg. Angewandte Chemie International ed. Perylene bisimides are among the most valuable functional dyes and have numerous potential applications. As a result of their chemical robustness, photostability, and outstanding optical and electronic properties, these dyes have been applied as pigments, fluorescence sensors, and n-semiconductors in organic electronics and photovoltaics.
However, the supramolecular approach to the formation of perylene bisimide aggregates has been restricted mostly to organic media. Pleasingly, considerable progress has been made in the last few years in developing water-soluble perylene bisimides and their application in aqueous media.

A generic statistical mech. The finite fibril width and helicity is shown to stem from a competition between the free energy gain from attraction between ribbons and the penalty because of elastic distortion of the intrinsically twisted ribbons on incorporation into a growing fibril. Fibers are stabilized similarly. The behavior of two rationally designed aa residue peptides, PI and PII, is illustrative of the proposed scheme.
The energetic parameters governing self-assembly have been estd. The model also provides a prescription of routes to novel macromols. Capito, Ramille M. We report here the self-assembly of macroscopic sacs and membranes at the interface between two aq. The formation of a diffusion barrier upon contact between the two liqs. We hypothesize that growth of the membrane is then driven by a dynamic synergy between osmotic pressure of ions and static self-assembly.
These robust, self-sealing macroscopic structures offer opportunities in many areas, including the formation of privileged environments for cells, immune barriers, new biol. We here present the principle of chiral self-assembly for the formation of lipid nanotube, its prepn.
