Silk reinforced carbon nanotubes spun by spiders is 3.5 times stronger than unaltered silk
The protein matrix and hard tissues of insects, worms, ants and spiders naturally incorporates metals, such as zinc, manganese and copper. This leads to mechanical hardening of teeth, jaws, mandibles, ovipositors and to an enhancement of silk toughness. Thus, the artificial incorporation of metals, or even insulating or semiconducting materials, into these protein structures could …
