The mechanical properties of spider silk are known to be dependent on spinning conditions. Here, the tensile behavior of over 1000 biomimetic spider silk fibers spun under 92 different conditions are tested, resulting in a yield strength of more than

Exposing spider silk to wet conditions can cause supercontraction. Here, tyrosine amino acid residues within the amorphous regions are found to contribute to supercontraction, which can be controlled by protein engineering.

Silk fibers derived from the cocoon of silk moths and the wide range of silks produced by spiders exhibit an array of features, such as extraordinary tensile strength, elasticity, and adhesive properties. The functional features and mechanical proper

Efficient production of artificial spider silk fibers with properties that match its natural counterpart has still not been achieved. Recently, a biomimetic process for spinning recombinant spider silk proteins (spidroins) was presented, in which imp

Herein we demonstrate a novel way of modifying the colloidal stability of proteins by the presence of hydrophobic molecules. A protein capable of self-assembly into protein nanofibrils (PNFs) is milled with a hydrophobic molecular material. Upon diss

Water and humidity severely affect the material properties of spider major ampullate silk, causing the fiber to become plasticized, contract, swell and undergo torsion. Several amino acid residue types have been proposed to be involved in this proces

Herein we utilize insulin to prepare amyloid based chiral heliceswith either right or left handed helicity. We demonstrate that thehelices can be utilized as structural templates for the conductingpolymer alkoxysulfonate poly(ethylenedioxythiophene)

Many proteins undergoe self-assembly into fibrillar structures known as amyloid fibrils. During the self-assembly process, related structures known as spherulites can be formed. Herein we report a facile method where the balance between amyloid fibri

The presence of a fluorescent hydrophobic oligothiophene (6T) dramatically influences the process where insulin self-assembles into spherulites, resulting in large (up to 1.4 mm) fluorescent spherulites.
