Spider silk has been an attractive biopolymer since ancient times. Learning from both its excellent properties and spinning process, silk provides people with inspiration to develop functional fi bers. Recently, inspired by shiny water droplets on a spider’s web, we revealed that the capture silk of the cribellate spider would deform to have a special periodic spindle-knots structure and hence displayed unique wettability, making it effi cient at directional watercollecting. This provides insights in designing functional fi bers with unique wettability, by either creating special structures on the fi ber surface, or modifying it with responsive molecules. These bioinspired functional fi bers may fi nd applications in many fi elds, such as water collection, smart catalysis, fi ltration, and sensing.
