A signature feature of living organisms is their ability to carry out purposeful actions by taking stock of the world around them. To that end, cells have an arsenal of signaling molecules linked together in signaling pathways, which switch between inactive and active conformations. The Molecular Switch articulates a biophysical perspective on signaling, showing how allostery—a powerful explanation of how molecules function across all biological domains—can be reformulated using equilibrium statistical mechanics, applied to diverse biological systems exhibiting switching behaviors, and successfully unify seemingly unrelated phenomena. Rob Phillips weaves together allostery and statistical mechanics via a series of biological vignettes, each of which showcases an important biological question and accompanying physical analysis. Beginning with the study of ligand-gated ion channels and their role in problems ranging from muscle action to vision, Phillips then undertakes increasingly sophisticated case studies, from bacterial chemotaxis and quorum sensing to hemoglobin and its role in mammalian physiology. He looks at G-protein coupled receptors as well as the role of allosteric molecules in gene regulation. Phillips concludes by surveying problems in biological fidelity and offering a speculative chapter on the relationship between allostery and biological Maxwell demons. Appropriate for graduate students and researchers in biophysics, physics, engineering, biology, and neuroscience, The Molecular Switch presents a unified, quantitative model for describing biological signaling phenomena.

The long-awaited second edition of the successful book covering molecular switches now in two volumes! Providing principles and applications this book brings you everything you need to know about molecular switches - a hot topic in the nanoworld. The major classes of molecular switches including catenanes, rotaxanes, azobenzenes together with polymer and biomolecular switching systems and DNA based switches are covered. Chemists and material scientists interested in one of the most innovative areas of their science will benefit greatly from reading this book. "This book will appeal most to organic chemists, because of the way new structures are introduced through their synthesis, but it will also provide a useful introduction for other scientists, provided they are conversant with molecular structures." (Organic and Biomolecular Chemistry) "... a comprehensive and up-to-date insight ..." (Chemistry & Industry)
Perfectly complements Biomolecular Information Processing, also by Prof. Katz, and available as a two-volume set. Edited by a renowned and much cited chemist, this book covers the whole span of molecular computers.

Perspectives in Supramolecular Chemistry will relate recent developments and new exciting approaches in supramolecular chemistry. In supramolecular chemistry, our aim is to understand molecular chemistry beyond the covalent bond - the series will concentrate on goal-orientated supramolecular chemistry. Perspectives in Supramolecular Chemistry will reflect research which develops supramolecular structures with specific new properties, such as recognition, transport and simulation of biosystems or new materials. The series will cover all areas from theoretical and modelling aspects through organic and inorganic chemistry and biochemistry to materials, solid-state and polymer sciences reflecting the many and varied applications of supramolecular structures in modern chemistry. Transition Metals in Supramolecular Chemistry Edited by Jean-Pierre Sauvage, Université Louis Pasteur, Strasbourg, France The chemistry of weak forces and non-covalent interactions as pioneered by Pedersen, Lehn and Cram is considered to be the origin of modern supramolecular chemistry. 30 years ago transition metals and their complexes were not regarded as important to this science. Transition Metals in Supramolecular Chemistry clearly demonstrates that today, transition metal complexes are routinely used to build large multicomponent architectures which display new and exciting applications including molecular switches, liquid crystals, and molecular magnets. Contents * Ligand and Metal Control of Self-Assembly in Supramolecular Chemistry * Bistability in Iron (II) Spin-Crossover Systems: A Supramolecular Function * Luminescent Sensors with and for Transition Metals * The Chirality of Polynuclear Transition Metal Complexes * Design and Serendipity in the Synthesis of Polynuclear Compounds of the 3d-metals * Rotaxanes: From Random to Transition Metal-Templated Threading of Rings at the Molecular Level * Metallomesogens - Supramolecular Organisation of Metal Complexes in Fluid Phases * Self-Assembly of Interlocked Structures with Cucurbituril Metal Ions and Metal Complexes Reflecting contemporary science, Transition Metals in Supramolecular Chemistry will inspire scientists and students interested in coordination chemistry, magnetochemistry, molecular sensors and switches, liquid crystals and artificial systems.
Switches Molecular switches , unlike the previous components , are devices that
have no single bulk analog . A switch is a device that can be programmed to be
either highly resistive ( open ) or highly conductive ( closed ) . Molecular switches
