Native-like Flow Properties of an Artificial Spider Silk Dope

Recombinant spider silk has emerged as a biomaterial that can circumvent problems associated with synthetic and naturally derived polymers, while still fulfilling the potential of native material. The artificial protein NT2RepCT be produced spun into fibers without use harsh chemicals here we evaluate key properties dope at native-like concentrations. We show recapitulates not only overall secondary structure content but also emulates its viscoelastic rheological properties. propose these are to biomimetic spinning optimization could facilitate successful dopes fibers.
