The silk of the recluse spider features a ribbon‐like morphology unlike any other spider silk or synthetically spun polymer fiber. These protein ribbons represent free‐standing polymer films with a thickness of about 50 nm. Stress–strain characterization of individual fibers via atomic force microscopy reveals that these ribbons, only a few molecular layers of protein thin, rival the mechanical performance of the best silks.
