Biological systems found in nature have inspired the studyand design of engineering systems and modern technology.For instance, some species of geckos have a unique abilityto quickly adhere to smooth vertical surfaces without theuse of liquids or surface tension. The biomimetic geckoadhesive mechanism has influenced engineers to designand build adhesive platforms aimed at achieving robustand efficiently scaled adhesion for climbing on invertedsurfaces with extreme topographical features. Similarly,sandcastle worms use a unique complex coacervate to gluetogether sand granules on the ocean floor whereas marinemussel adhesion is less specific and certainly more oppor-tunistic than typical ligand-receptor interactions in proteinadhesion. Adhesion in such marine organism is notewor-thy due to its ability to overcome moisture and its abilityto realize strong and reliable adhesion under water thatmost fabricated adhesives are lacking. Nature has developedsurprisingly varied and, at times, rather ingenious lubricationstrategies for controlling and regulating the interactionforces, friction, and wear at sheared interfaces; for example,the superlubricity and wear protection properties conferredby the complex synergy between the various proteins,polysaccharides, and lipids in the synovial fluid betweenarticular joints in animals are rather startling. In thisspecial issue, authors have discussed biomimicry techniquesand ideas to engineer materials for imprinting technology,antibacterial surfaces, drag mitigating interfaces, impact-

resistant materials, and load bearing composites. Mathemat-ical models have been used to explain the physics of thesuperior properties of the biomimetic materials. The practi-cal use of the published research has been demonstrated byprototypes that mimic biological organisms.
