“…For patterns of unmodified spider silk fibers, there appears one characteristic broad peak, which is located at 2θ = 10.58°, corresponding to typical XRD spider silk patterns. 74 Whereas the peaks were not substantially altered after spider silk modification, the alcohol treatment and UCNPs insertion does not seem to affect and reverse the spidroin structure in the spider silk fibers.…”

Spider silk is a natural material possessing unique properties such as biocompatibility, regenerative and antimicrobial activity, and biodegradability. It is broadly considered an attractive matrix for tissue regeneration applications. Optical monitoring and potential control over tissue regrowth are attractive tools for monitoring of this process. In this work, we show upconversion modification of natural spider silk fibers with inorganic nanoparticles. To achieve upconversion, metal oxide nanoparticles were doped with low concentrations of rare-earth elements, producing potentially biocompatible luminescent nanomaterials. The suggested approach to spider silk modification is efficient and easy to perform, opening up sensing and imaging possibilities of biomaterials in a noninvasive and real-time manner in bio-integration approaches.

“…NSSRs have strong crystallization peaks at 12.2 ° , 20.1 ° , 23.3 ° , and 26.8 ° (Figure 4e), which are slightly different from Nephila pilipes , Argiope pulchella , and Stegodyphus sarasinorum spider silk. [ 39 ] RSSRs only show broad diffraction peaks at 13.5–18.5 ° and 21.4–24.1 ° . S‐RSSRs show an obvious crystalline peak at 2 θ = 20.1 ° , which represents more β ‐crystallites structure than RSSRs.…”

Natural spider silks with striking performances achieve extensive investigations. Nonetheless, a lack of consensus over the mechanism of the natural spinning hinders the development of artificial spinning methods where the regenerated spider silks generally show poor performances compared with the natural fibers. As is known, the Plateau–Rayleigh instability tends to break solution column into droplets and is considered a main challenge during fiber‐spinning. Here in this study, by harnessing the viscoelastic properties of the regenerated spidroin dope solution via organic salt–zinc acetate (ZA), this outcome can be avoided, and dry‐spinning of long and mechanically robust regenerated spider silk ribbons can be successfully realized. The as‐obtained dry‐spun spider silk ribbons show an enhanced modulus up to 14 ± 4 GPa and a toughness of ≈51 ± 9 MJ m−3 after the post‐stretching treatment, which is even better than that of the pristine spider silk fibers. This facile and flexible strategy enriches the spinning methodologies which bypass the bottleneck of precisely mimicking the complex natural environment of the glands in spiders, shining a light to the spider‐silk‐based textile industrial applications.

“…92 In nature, spiders secrete liquid proteins through different glands to form a gel mixture, followed by spinning them into solid fiber. 93 To prepare PAA−alginate hard hydrogel microfibers sustainably on a large scale, Wei et al applied biomimetic microfluidic devices as printing heads and the microfluidic nozzles comprised two coaxially aligned channels for injecting core and sheath liquids. 94 linking agent, photoinitiator, and sodium alginate polymer were used as the sheath liquid phase for 3D printing.…”
