Physical Chemistry Of Biological Interfaces

An introduction to the most important fundamental concepts of physicochemical interface science and a description of experimental techniques and applications of surface science in relation to biological systems. It explores artificial assemblies of lipids, proteins and polysaccharides that perform novel functions that living systems cannot duplicate.

Electrified interfaces span from metaVsemiconductor and metaVelectrolyte interfaces to disperse systems and biological membranes, and are notably important in so many physical, chemical and biological systems that their study has been tackled by researchers with different scientific backgrounds using different methodological approaches. The various electrified interfaces have several common features. The equilibrium distribution of positive and negative ions in an electrolytic solution is governed by the same Poisson-Boltzmann equation independent of whether the solution comes into contact with a metal, a colloidal particle or a biomembrane, and the same is true for the equilibrium distribution of free electrons and holes of a semiconductor in contact with a different conducting phase. Evaluation of electric potential differences across biomembranes is based on the same identity of electrochemical potentials which holds for a glass electrode and which yields the Nernst equation when applied to a metal/solution interface. The theory of thermally activated electron tunneling, which was developed by Marcus, Levich, Dogonadze and others to account for electron transfer across metaVelectrolyte interfaces, is also applied to light induced charge separation and proton translocation reactions across intercellular membranes. From an experimental viewpoint, the same electrochemical and in situ spectroscopic techniques can equally well be employed for the study of apparently quite different electrified interfaces.

Colloidal systems occur everywhere—in soils, seawater, foodstuff, pharmaceuticals, paints, blood, biological cells, and microorganisms. Colloids and Interfaces in Life Sciences and Bionanotechnology, Second Edition, gives a concise treatment of physicochemical principles determining interrelated colloidal and interfacial phenomena. New in the Second Edition: New topics, including phase separations in polymer systems, electrokinetics of charged permeable surface coatings, and polymer brush coatings to control adsorption and adhesion of particles Emphasis on inter-particle interactions and surface phenomena in (bio)nanotechnology Full solutions to over 100 updated and additional exercises are presented in the Appendix Focusing on physicochemical concepts that form the basis of understanding colloidal and interfacial phenomena—rather than on experimental methods and techniques—this book is an excellent primer for students and scientists interested in colloidal and interfacial phenomena, their mutual relations and connections, and the fascinating role they play in natural and man-made systems.

Interfacial science impacts on our lives in diverse and surprising ways. Without it, we would face bubble bath without the bubbles, detergents which don't clean, cappuccinos without the froth. It has also fuelled some of the most ground-breaking and thought-provoking advances in research in the last decade, from biosciences to nanotechnology. Interfacial Science: An Introduction offers an engaging insight into the study of the physical and chemical properties of interfaces, how they behave, why they behave as they do, and how this behaviour can be harnessed and exploited. Opening with an overview of the key principles of capilliarity and adsorption, the book goes on to explore liquid/gas, solid/gas, and liquid/liquid interfaces, before examining biological interfaces, one of the most stimulating areas of current research. With the careful explanation of essential mathematical and physical concepts, and description of real world applications of the material presented, the book helps the student to build confidence in, and see the relevance of, the topics covered. Striking a careful balance between the highly mathematical treatments of the subject by more specialist texts, and the rudimentary treatment offered by general physical chemistry texts, Interfacial Science: An Introduction offers a breadth and depth of treatment which is perfect for any advanced undergraduate course on this exciting, dynamic subject.

Serving as a general introduction to surface and interface science, this book focuses on essential concepts rather than specific details, on intuitive understanding rather than learning facts. The text reflects the fact that the physics and chemistry of surfaces is a diverse field of research and shows this in its Interdisciplinary conceptual design. Once the most important techniques and methods have been introduced, readers will be able to apply simple models to their own scientific problems. Furthermore, manifold high-end technological applications from surface technology, biotechnology, or microelectronics illustrate the basic scientific treatment. The authors address advanced students of chemistry, physics, materials science, chemical engineering and related subjects with a basic knowledge of natural sciences and mathematics, since the mathematical calculations are thoroughly explained and made comprehensible for the reader. As such, non-specialists in surface science who want to learn more about this important subject will also benefit from the book.

Provides a comprehensive treatment of surface chemistry and its applications to chemical engineering, biology, and medicine. Focuses on the chmical and physical structure of oil-water interfaces and membrane surfaces. Details interfacial potentials, ion solvation, and electrostatic instabilities in double layers.

Success or failure of biomaterials, whether tissue engineered constructs, joint and dental implants, vascular grafts, or heart valves, depends on molecular-level events that determine subsequent responses of cells and tissues. This book presents the latest developments and state-of-the-art knowledge regarding protein, cell, and tissue interactions with both conventional and nanophase materials. Insight into these biomaterial surface interactions will play a critical role in further developments in fields such as tissue engineering, regenerative medicine, and biocompatibility of implanted materials and devices. With chapters written by leaders in their respective fields, this compendium will be the authoritative source of information for scientists, engineers, and medical researchers seeking not only to understand but also to control tissue-biomaterial interactions.
