a Regenerated B. mori silk fibers dip-coated with gelatin. (i) Scheme of the production of the spindle knot fibers. (ii) SEM images of the morphology of the fabricated fibers coated with 10% gelatin. (iii) Stress-strain curves of degummed silk fibroin fibers (red) and various treated gelatin-coated fibers. Black: freshly prepared gelatin-coated fiber; blue: treated gelatin-coated fiber stored at 40 °C and 30% humidity (15 days); green: gelatin-coated fiber stored for 1 year. (iv) Water collecting properties of the gelatin-coated fiber at ~95% relative humidity.

A core-shell silk fiber consisting of B. mori silk protein (core) coated with recombinant major ampullate silk protein (MaSp2) allowed the formation of knots on the fiber surface after drying. These fibers enabled water collection from the surrounding environment. Adapted and modified with permission from ref. 188, copyright John Wiley and Sons, 2020.
