Adhesion is a chemical or mechanical effect of substances used by organisms to construct domiciles, capture prey, secure offspring, and navigate complex environments. This symposium has been curated to showcase creative research on sticky biomaterial properties, production, and applications by incorporating speakers with diverse study systems, including plants, mollusks, arthropods, and vertebrates. With new progress in sequencing technologies, increasing knowledge of the natural history of organisms that produce adhesive materials, and the development of flexible methods and instrumentation for measuring fine forces, we hope that this symposium will encourage progress on biomimetics and appreciation for the biochemical array of adhesives found in nature.
