TL;DR: In this paper, the authors used oscillatory rheology, Fourier transform infrared spectroscopy, and circular-dichroism spectrograms to understand the assembly mechanism of a typical PE molecule known as PA-1, which is triggered by counterion screening and stabilized by van der Waals and hydrophobic forces.

TL;DR: The synthesis of magnetic resonance (MR) active peptide amphiphile molecules that self-assemble into spherical and fiber-like nanostructures, enhancing T(1) relaxation time is reported, which can potentially be used to combine high-resolution three-dimensional MR fate mapping of tissue-engineered scaffolds with targeting of specific cellular receptors.

TL;DR: A method to prepare a hybrid bone implant material consisting of a Ti-6Al-4V foam, whose 52% porosity is filled with a peptide amphiphile (PA) nanofiber matrix, to improve fixation, osteointegration, and long term stability of implants is reported on.

TL;DR: In this paper, a self-assembling peptide amphiphiles (PAs) were synthesized in order to form high-aspect-ratio nanofibers with internal order that can present imidazolyl groups capable of ester hydrolysis.

TL;DR: Self-assembling supramolecular nanofibers that display the cell adhesion ligand RGDS at van der Waals density to cells are used and it is found that branched architectures of the monomers and the consequent lower packing efficiency and additional space for epitope motion improves signaling forcell adhesion, spreading, and migration.
