Correlation Between Processing Conditions, Microstructure and Mechanical Behavior in Regenerated Silkworm Silk Fibers [PDF]

, 2012
Regenerated silkworm fibers spun through a wet-spinning process followed by an immersion postspinning drawing step show a work to fracture comparable with that of natural silkworm silk fibers in a wide range of spinning conditions.

THE FINE STRUCTURE OF SILK FIBROIN [PDF]

The Journal of Cell Biology, 1967
The fine structure of Bombyx mori silk fibroin was investigated by electron microscopy and X-ray diffraction techniques. Examination of silk fibers fragmented with ultrasonic radiation and negatively stained revealed the presence of ribbon-like filaments of well-defined lateral dimensions. Analysis of the breadths of the equatorial reflections in the X-

Conservation of a pH-sensitive structure in the C-terminal region of spider silk extends across the entire silk gene family [PDF]

, 2018
Spiders produce multiple silks with different physical properties that allow them to occupy a diverse range of ecological niches, including the underwater environment. Despite this functional diversity, past molecular analyses show a high degree of amino

Silk fibroin electrogelation mechanisms [PDF]

Acta Biomaterialia, 2011
A silk fibroin gel system (e-gel), formed with weak electric fields, has potential utility in medical materials and devices. The mechanism of silk e-gel formation was studied to gain additional insight into the process and control of the material properties.

Influence of adding multiwalled carbon nanotubes on the adhesive strength of composite epoxy/sol–gel materials [PDF]

, 2016
The tensile shear strength of a composite epoxy/sol–gel system modified with different ratios of multiwall carbon nanotubes (MWCNTs) was evaluated using a mechanical testing machine.

A silk composite fiber reinforced by telechelic-type polyalanine and its strengthening mechanism [PDF]

, 2022
Antiparallel β-sheets play a key role in determining the physical properties of fibroins, e.g., degradation and mechanical properties, and are typically formed by poly(A) motifs from spider dragline silks and GAGAGS motifs from Bombyx mori silkworm silks.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create
