This book reviews the structure of different biological adhesives and the mechanisms by which they achieve interfacial adhesion, cohesive strength, and fracture toughness. These adhesives include cements, strongly adherent fibrous holdfasts, tough and flexible adhesive gels, energy-dissipating adhesive tapes, nanoparticle-based adhesives, hierarchically structured nanoarray adhesives and a wide variety of viscous, sticky secretions. Biological adhesives are complex biomaterials that have evolved to meet a wide variety of functional demands, and which range from the micro- to the macro-scale. Some adhesives set rapidly, while others set over longer periods of time; others can readily detach and reattach to allow movement and to manipulate objects, while yet others have the ability to self-heal after sustaining damage. Recent technological advances have expanded our ability to characterize these materials. Analyzing the physical and molecular structure, processing, chemical interactions and mechanical properties of these adhesives has yielded novel insights, which this new edition discusses in detail. These insights are likely to inform and guide the biomimetic development of new, powerful adhesives with desirable properties that are unmatched by today's synthetic adhesives. Given the breadth and depth of its coverage, the book offers an invaluable source of information for industrial and academic researchers alike.

Zusammenfassung

Many plants, animals, and microbes use adhesive polymers and structures to attach to inert substrates, to each other, or to other organisms. This is the first major review that brings together research on many of the well-known biological adhesives. Emphasizing the diversity of biological adhesives and associated adhesion processes, it deals with bacteria, fungi, algae, and marine and terrestrial animals. It bridges a variety of disciplines including biochemistry, molecular biology, biomechanics, bioengineering, microbiology, organism structure and function, and ultrastructure. As we learn more about the molecular and mechanical properties of these adhesives, we begin to understand why they adhere so well and how they develop cohesive strength. With this understanding comes the prospect of developing synthetic or semi-synthetic adhesives with broad applications in areas such as medicine, dentistry, and biotechnology. The book is suitable for both industrial and academic researchers.
