In this work, a novel self‐healing material is generated using spider silk. Dragline silk from spider Nephila pilipes is demonstrated with extraordinary in situ self‐repair property through a constructed thin film format, surpassing that of two other silks from spider Cyrtophora moluccensis and...

Additionally, the spider silk‐inspired heterogeneous structures enhance mechanical properties. Furthermore, the incorporation of TA provides enhances adhesion, as well as remarkable antibacterial and antioxidant properties. This innovative hyaluronic acid‐based hydrogel, inspired by spider sil...

Spider phobia is a common specific phobia, particularly in females, and can negatively impact quality of life. The dataset offers valuable insights into understanding and treating spider phobia, including subjective levels of fear, disgust, and willingness to approach spiders. ...
Spider dragline silk's exceptional mechanical performance, coupled with its benign production pathway, have inspired the design of diverse smart materials. Remarkably, relatively little is known about the self‐assembly process of major ampullate spidroin 1 (MaSp1) – the main pro...
Furthermore, the recombinant spider silk as a dry coating material demonstrated self-healing under humidity as well as cell affinity. The electrical conductivity of the dry silk coating was ~0.4 mS/m. Neural stem cells (NSCs) proliferated on the coated surface and showed a 2.3-fold...
