Abstract

Spiders use pyriform silk as an adhesive for the attachment of webs to a variety of surfaces. “Staple pin” architecture is an efficient architectural design used by spiders to lay multiple pyriform fibers on the underlying dragline silk. On page 553, Dharamdeep Jain, Vasav Sahni, and Ali Dhinojwala use electrospinning to fabricate a synthetic adhesive attachment staple pin. The cover collage of four scanning electron microscopy images shows the underlying nylon fiber (30-micron diameter) covered with electrospun polyurethane fibers on an aluminum substrate. The spacing can be controlled using the collector speed. The architectural design holds potential for producing adhesives for applications in biomedical and consumer industries.
