Abstract in another language

Major ampullate (MA) spider silk reveals outstanding mechanical properties in terms of a unique combination of high tensile strength and extensibility, unmatched by most other known native or synthetic fiber materials. MA silk contains at least two spider silk proteins (spidroins), and here, a novel two-in-one (TIO) spidroin was engineered, resembling amino acid sequences of such two of the European garden spider. The combination of mechanical and chemical features of both underlying proteins facilitated the hierarchical self-assembly into β-sheet-rich superstructures. Due to the presence of native terminal dimerization domains, highly concentrated aqueous spinning dopes could be prepared from recombinant TIO spidroins. Subsequently, fibers were spun in a biomimetic, aqueous wet-spinning process, yielding mechanical properties at least twice as high as fibers spun from individual spidroins or blends. The presented processing route holds great potential for future applications using ecological green high-performance fibers.
