Toward 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 کاملSilk Spinning in Silkworms and Spiders
Spiders and silkworms spin silks that outcompete the toughness of all natural and manmade fibers. Herein, we compare and contrast the spinning of silk in silkworms and spiders, with the aim of identifying features that are important for fiber formation. Although spiders and silkworms are very distantly related, some features of spinning silk seem to be universal. Both spiders and silkworms prod...
متن کاملSex differences in cooperative silk-spinning by weaver ant larvae.
Final-instar larvae of weaver ants (Oecophylla longinoda) use their silk for nest construction rather than for cocoon spinning; this commitment represents a shift from entirely selfish to entirely cooperative behavior that occurred after the emergence of the phylogenetically advanced subfamily Formicinae. Male larvae were found to have smaller silk glands and to contribute substantially less si...
متن کاملSilk from Crickets: A New Twist on Spinning
Raspy crickets (Orthoptera: Gryllacrididae) are unique among the orthopterans in producing silk, which is used to build shelters. This work studied the material composition and the fabrication of cricket silk for the first time. We examined silk-webs produced in captivity, which comprised cylindrical fibers and flat films. Spectra obtained from micro-Raman experiments indicated that the silk is...
متن کاملRecent Advances in Gene Technology of Silk Spinning Insects
Among Iepidopteran insects, species belonging to the Bombycidae, Saturniidae and a few other genera have been traditionally used for the silk production. However, recently developed knowledge on the basic i-nolecular bioiogy of these sUk spinning in$ects,, especially Bombyx mori, has guided u$ towards advanced gene technology for their novel beneficial applications. Establishment ofa baculoviru...
