Background Combining high strength and elasticity, spider silks are exceptionally tough, i.e., able to absorb massive kinetic energy before breaking. Spider silk is therefore a model polymer for development of high performance biomimetic fibers. There are over 41.000 described species of spiders, most spinning multiple types of silk. Thus we have available some 200.000+ unique silks that may cover an amazing breadth of material properties. To date, however, silks from only a few tens of species…

Multicomponent nature underlies the extraordinary mechanical properties of spider dragline silk
Artificial synthesis and the combination of these components in vitro showed that the multicomponent nature of dragline Silk, including MaSp3B and SpiCE, along with MaSp1 and MaSp2, is essential to realize the mechanical properties of spider dragline silk.
The transcriptome of Darwin’s bark spider silk glands predicts proteins contributing to dragline silk toughness
A suite of novel traits from the level of genes to spinning physiology to silk biomechanics are associated with the unique ecology of Darwin’s bark spider, presenting innovative designs for engineering biomaterials.
The Thin Ribbon Silk of the Brown Recluse Spider: Structure, Mechanical Behavior, and Biomimicry
Silk has enormous potential as a next-generation material: it is a biopolymer spun from protein at ambient temperature and pressure, and the best spider silks are as strong as steel and tougher than
Strength of Recluse Spider's Silk Originates from Nanofibrils.
Spider silk exhibits a combination of outstanding tensile strength and extensibility unique among all synthetic and biogenic polymer fibers. It has thus generated great interest to understand
Synthetic Spider Silk Proteins and Threads
Silk is an amazing material produced naturally by various species, such as the silk moth and silk worm (Lepidoptera), bees, wasps, and ants (Hymenoptera), and spiders (arthropods). Each species’ silk
Spider silk as a blueprint for greener materials: a review
Spider silk exhibits remarkable properties, especially its well-known tensile performances. They rely on a complex nanostructured hierarchical organisation that studies progressively elucidate.
High-performance spider webs: integrating biomechanics, ecology and behaviour
An integrative, mechanistic approach to understanding silk and web function, as well as the selective pressures driving their evolution, will help uncover the potential impacts of environmental change and species invasions on spider success.
A study of the extraordinarily strong and tough silk produced by bagworms
The properties and structure of Bagworm silk are studied and it is reported as being extraordinarily strong and tough compared to other known silks.
Characterization of the genome and silk-gland transcriptomes of Darwin’s bark spider (Caerostris darwini)
Draft genomic and transcriptomic assemblies of Darwin’s bark spider, Caerostris darwini, an orb-weaving spider whose dragline is one of the toughest known biomaterials on Earth are reported.
Spider Silks and Their Biotechnological Applications
The relationship between molecular composition, secondary structure, and mechanical properties of spider silks is described in this chapter, along with a discussion of the current strategies for the production of recombinant silks, their importance in new biotechnological applications, and the current status of the field.


Spider capture silk: performance implications of variation in an exceptional biomaterial.
A large comparative data set is presented that allows examination of capture silk properties across orb-weaving spider species, finding that material properties vary greatly across species and some material and mechanical properties are evolutionarily correlated.
Variation in the material properties of spider dragline silk across species
It is suggested that the spectrum of dragline silk sequences and material properties that have been produced over evolutionary time provides a rich resource for the design of biomimetic silk fibers.
The evolution of complex biomaterial performance: The case of spider silk.
New data on material properties of silk from nine species of spiders in the Mesothelae and Mygalomorphae, the two basal clades of spiders, support the hypothesis that the success and diversity seen in araneomorph spiders is associated with the evolution of this high-performance fiber.
Spider silk as a novel high performance biomimetic muscle driven by humidity
It is shown that silk also exhibits powerful cyclic contractions, allowing it to act as a high performance mimic of biological muscles, and the potential applicability of silk muscles is further enhanced by the finding that silkworm fibers also exhibit cyclic contraction because they are already available in commercial quantities.
Material properties retain different levels of phylogenetic signal, suggesting that traits such as extensibility and toughness may be subject to different types or intensities of selection in several spider lineages.
The evolution of the material properties of dragline silk across a phylogenetically diverse sample of species in the Araneomorphae (true spiders) show that the properties of biological materials are the target of selection, and that these changes can produce evolutionarily and ecologically important diversity.
Mechanical behavior of silk during the evolution of orb-web spinning spiders.
The comparison of silks spun by spiders belonging to different phylogenetic groups has revealed that evolution locked in many of the important properties of spider silks very early in the history of orb-web weaving spiders, despite the fact that the silk gland system is relatively isolated in physiological terms from the rest of the organism and should thus mutate quickly.
Silks as ancient models for modern polymers
Behavioural and biomaterial coevolution in spider orb webs
Spider silk material properties are fine‐tuned to the architectures of webs across millions of years of diversification, a coevolutionary pattern not yet clearly demonstrated for other important biomaterials such as tendon, mollusc byssal threads, and keratin.
