Available in PDF, EPUB and Kindle. Book excerpt: Intimate molecular contact at joint interfaces is essential for the extremely localized surface forces to result in adhesion exceeding the cohesive strength of the joined materials. Liquids, however viscous, are perhaps a more important class of adhesives in biology than in any other field. Attention is focused on the spreading of well-defined liquids over rigid or coherent phases of potential biological interest. The contact angle (T) of liquids on solids provides an inverse measure of liquid spreading. Rectilinear plots of cos T vs liquid surface tension (L) define the critical surface tension of wetting (Lc) for each solid. Direct, simple correlations exist between Lc and solid surface composition. Wetting and adhesion can be completely changed by adsorbed films, even monolayers; adsorbed water, for example, can markedly decrease Lc. Wettability properties and Lc concept are pertinent to current adhesional and biomedical problems. Coupling agents have a potential role in bioadhesion. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, bacterial adhesion has become a more and more important and active scientific area, but the field lacks communication and scientific exchange between medical and microbiology researchers who work with the relevant biological systems, and biochemists, structural biologists and physicists, who know and understand the physical methods best suited to investigate the phenomenon at the molecular level. The field consequently would benefit from a cross-disciplinary conference enabling such communication. This book tries to bridge the gap between the disciplines.

This book was released on 2013-11-11 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: By employing a combination of approaches from several disciplines the authors elucidate the principles of a variety of biomechanical systems that rely on frictional surfaces or adhesive secretions to attach parts of the body to one another or to attach organisms to a substrate. This account provides an excellent starting point for engineers and physicists working with biological systems and for biologists studying friction and adhesion. It will also serve as a valuable introduction for graduate students entering this interdisciplinary field of research.

Available in PDF, EPUB and Kindle. Book excerpt: Many creatures 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 dealing with bacteria, fungi, algae, and marine and terrestrial animals. As we learn more about their molecular and mechanical properties we begin to understand why they adhere so well and with this comes broad applications in areas such as medicine, dentistry, and biotechnology.

Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Annual Pezcoller Symposium entitled Adhesion Molecules: Cellular Recognition Mechanisms was held in Rovereto, Italy, June 24-26, 1992 and was focussed on the detailed mechanisms whereby cells utilize certain integral membrane proteins to perceive their surrounding environment and interact with it. With timely presentations and stimulating discussions this Symposium addressed the genetics and biochemistry of adhesion molecules, the regulation of their functions and their role in cancer and the immune system. Emphasis was given to adhesion proteins in the integrin family because of the widespread distribution of this group of molecules and its important role in essentially all eukaryotic biological systems. The regulation of integrin genes and their expression are discussed in detail, as are specific aspects of the genetics of fibronectin. The molecular basis for the regulation of certain integrins, the function of these proteins in determining cell adhesion, and the consequences of this adhesion for the function of the cells involved are discussed. The role of certain integrins in stimulating signal transduction, the essential involvement of integrins in conditioning the function of T and NK cells function, the heterogeneity of integrins and its biological consequences, and the role of cell adhesion molecules in tumor cells invasion and metastases are all extensively analyzed. New information was presented on the role of CD44 and splice variants in normal differentiation and tumor progression.
Download or read book Scaling Reversible Adhesion in Synthetic and Biological Systems written by Michael David Bartlett and published by . This book was released on 2013 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geckos and other insects have fascinated scientists and casual observers with their ability to effortlessly climb up walls and across ceilings. This capability has inspired high capacity, easy release synthetic adhesives, which have focused on mimicking the fibrillar features found on the foot pads of these climbing organisms. However, without a fundamental framework that connects biological and synthetic adhesives from nanoscopic to macroscopic features, synthetic mimics have failed to perform favorably at large contact areas. In this thesis, we present a scaling approach which leads to an understanding of reversible adhesion in both synthetic and biological systems over multiple length scales. We identify, under various loading scenarios, how geometry and material properties control adhesion, and we apply this understanding to the development of high capacity, easy release synthetic adhesive materials at macroscopic size scales. Starting from basic fracture mechanics, our generalized scaling theory reveals that the ratio of contact area to compliance in the loading direction, A/C, is the governing scaling parameter for the force capacity of reversible adhesive interfaces. This scaling theory is verified experimentally in both synthetic and biological adhesive systems, over many orders of magnitude in size and adhesive force capacity (Chapter 2). This understanding is applied to the development of gecko-like adhesive pads, consisting of stiff, draping fabrics incorporated with thin elastomeric layers, which at macroscopic sizes (contact areas of 100 cm2) exhibit force capacities on the order of 3000 N. Significantly, this adhesive pad is non-patterned and completely smooth, demonstrating that fibrillar features are not necessary to achieve high capacity, easy release adhesion at macroscopic sizes and emphasizing the importance of subsurface anatomy in biological adhesive systems (Chapter 2, Chapter 3). We further extend the utility of the scaling theory under shear (Chapter 4) and normal (Chapter 5) loading conditions and develop simple expressions for patterned and non-patterned interfaces which describe experimental force capacity data as a function of geometric parameters such as contact area, aspect ratio, and contact radius. These studies provide guidance for the precise control of adhesion with enables the development of a simple transfer printing technique controlled by geometric confinement (Chapter 6). Force capacity data from each chapter, along with various literature data are collapsed onto a master plot described by the A/C scaling parameter, with agreement over 15 orders of magnitude in adhesive force capacity for synthetic and biological adhesives, demonstrating the generality and robustness of the scaling theory (Chapter 7).

Available in PDF, EPUB and Kindle. Book excerpt: Due to their impressive performance biological adhesives have inspired the development of superior industrial adhesives. Biological adhesives often provide elegant solutions to engineering and biomedical requirements and are expected to inspire future technological innovations for adhesives for use in hostile conditions. Containing a selection of papers presented at the 1st International Conference on Biological and Biomimetic Adhesives, this book will showcase the latest advances in the chemical and structural characterisation of adhesives, the mechanical testing of adhesives and theory, fabrication and applications of biomimetic adhesives. Following the work of COST Action TD0909, the aim is to gain greater understanding of the mode of action of biological adhesives to allow successful development of improved synthetic counterparts. Appealing to a wide range of researchers in biology, chemistry, physics and engineering, the title provides the background and drive to improve scientific and technological progress in this important area.
