  • The silks produced by spiders are exceptional structural materials. Although their tensile strengths are similar to those of cellulose, collagen and chitin, their extensibilities are considerably greater1,2. Thus, the energy required to break spider silk (that is, its toughness) can be 10 times greater than for these other biological materials. The silks are crystalline proteins, with substantial portions of their polypeptide chains forming crystallites of stacked β -pleated sheets3–6. However… CONTINUE READING
