Spider Silk
Some things about spider silk are difficult to understand.The genetic code for one of the more perplexing types of silk—the strands spiders use to weave their egg cases. Each case must be tough enough to keep out parasites, impermeable to rain and fungus, and breathable while insulating eggs from temperature extremes. These qualities alone would make an impressive fabric.The egg cases may even ...
متن کاملSpider silk reduces insect herbivory.
The role of predators in food webs extends beyond their ability to kill and consume prey. Such trait-mediated effects occur when signals of the predator influence the behaviour of other animals. Because all spiders are silk-producing carnivores, we hypothesized that silk alone would signal other arthropods and enhance non-lethal effects of spiders. We quantified the herbivory inflicted by two b...
متن کاملEngineering Properties of Spider Silk
Motivated by the high level of strength and toughness of spider silk and its multifunctional nature, this paper reports on the engineering properties of individual fibers from Nephila Clavipes spider drag line under uniaxial tension, transverse compression and torsional deformation. The tensile properties were compared to the Argiope Aurentia spider silk and show different ultimate strength but...
متن کاملToward spinning artificial spider silk.
Spider silk is strong and extensible but still biodegradable and well tolerated when implanted, making it the ultimate biomaterial. Shortcomings that arise in replicating spider silk are due to the use of recombinant spider silk proteins (spidroins) that lack native domains, the use of denaturing conditions under purification and spinning and the fact that the understanding of how spiders contr...
متن کاملBiomineralization of Engineered Spider Silk
Materials based on biodegradable polyesters such as poly(butylene terephthalate) (PBT) 20 or poly(butylene terephthalate-co-poly(alkylene glycol) terephthalate) (PBTAT) have potential 21 application as pro-regenerative scaffolds for bone tissue engineering. Herein is reported the 22 preparation of films composed of PBT or PBTAT and an engineered spider silk protein, 23 (eADF4(C16)), that displa...
