Casting Metal Nanowires Within Discrete Self-Assembled Peptide Nanotubes
TLDR
The observation of the self-assembly of a very short peptide, the Alzheimer's β-amyloid diphenylalanine structural motif, into discrete and stiff nanotubes, resulted in the production of discrete nanowires with a long persistence length.
Self-assembled peptide nanotubes are uniquely rigid bioinspired supramolecular structures.
TLDR
This work finds that the averaged point stiffness of the nanotubes is 160 N/m, and that they have a correspondingly high Young's modulus of approximately 19 GPa, as calculated by finite element analysis.
Elementary building blocks of self-assembled peptide nanotubes.
TLDR
An exceptional quantum-confined approach is shown here for the self-assembly mechanism in bio-inspired materials, finding the elementary building block of the studied PNT, which is self-assembled from short peptides composed of two phenylalanine residues, to be 0D-quantum-confinement, also called a quantum dot (QD).
Quantum confinement in self-assembled bioinspired peptide hydrogels.
TLDR
This work examined the optical properties, optical absorption and photoluminescence of hydrogels that were self-assembled from Fmoc-FF building blocks, and followed the formation of a quantum confined structure within the hydrogel nanotubes.
Strong piezoelectricity in bioinspired peptide nanotubes.
TLDR
Anomalously strong shear piezoelectric activity in self-assembled diphenylalanine peptide nanotubes (PNTs) is shown, indicating electric polarization directed along the tube axis, opening up a wide avenue for developing new generations of "green" piezOElectric materials and piezonanodevices based on bioactive tubular nanostructures potentially compatible with human tissue.
Blue luminescence based on quantum confinement at peptide nanotubes.
TLDR
The estimations show that QC in these nanotubes occurs due to a crystalline structure of subnanometer scale dimension formed under the self-assembly process, paving the way for the integration of PNT in a new generation of optical devices.
