Spider Silk: Thousands of Nano-Filaments and Dollops of Sticky Glue
Some spiders use glues while others deploy strands of fine filaments for fixing flies. Recent work has provided new insights into the mechanical properties of these nano-scale ropes.
متن کاملUbiquitous distribution of salts and proteins in spider glue enhances spider silk adhesion
Modern orb-weaving spiders use micron-sized glue droplets on their viscid silk to retain prey in webs. A combination of low molecular weight salts and proteins makes the glue viscoelastic and humidity responsive in a way not easily achieved by synthetic adhesives. Optically, the glue droplet shows a heterogeneous structure, but the spatial arrangement of its chemical components is poorly unders...
متن کاملEvidence from Multiple Species that Spider Silk Glue Component ASG2 is a Spidroin
Spiders in the superfamily Araneoidea produce viscous glue from aggregate silk glands. Aggregate glue coats prey-capture threads and hampers the escape of prey from webs, thereby increasing the foraging success of spiders. cDNAs for Aggregate Spider Glue 1 (ASG1) and 2 (ASG2) have been previously described from the golden orb-weaver, Nephila clavipes, and Western black widow, Latrodectus hesper...

متن کاملUnraveling the mechanical properties of composite silk threads spun by cribellate orb-weaving spiders.
Orb-web weaving spiders depend upon the mechanical performance of capture threads to absorb the energy of flying prey. Most orb-weavers spin wet capture threads with core fibers of flagelliform silk. These threads are extremely compliant and extensible due to the folding of their constituent proteins into molecular nanosprings and hydration by a surrounding coating of aqueous glue. In contrast,...
