TLDR
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.Abstract:
The self assembly of peptide hydrogelators that carry aromatic substituents can be modeled by a novel nanocylindrical architecture. The proposed model suggests that the nanocylinders are formed by anti-parallel β-sheets interlocked by the π-stacking interactions of fluorenyl groups and phenyl rings. This explanation is consistent with the structures observed in TEM and the data obtained by a variety of spectroscopic techniques.read more

Molecular self-assembly and nanochemistry: a chemical strategy for the synthesis of nanostructures.
TL;DR: The ability to prepare structures in the upper part of this range of sizes 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.

Spontaneous assembly of a self-complementary oligopeptide to form a stable macroscopic membrane.
TL;DR: This work has shown that a 16-residue peptide has a characteristic beta-sheet circular dichroism spectrum in water and spontaneously assembles to form a macroscopic membrane, which may be a model for studying the insoluble peptides found in certain neurological disorders.
