The advances in both molecular biology and the physics of irreversible processes have offered hope for understanding living systems in terms of the known physical laws, and thus we shall be able to see life as one of the many phenomena displayed by the universe in its evolution. This book is an attempt to introduce physicists and physically-oriented students of the biological sciences to this view. An introductory discussion of the definition of ?living? is followed by an overview of the properties of living systems as we know them. Then selected topics, chosen because of their fundamental importance to our understanding of living systems, are presented in greater detail. This book is therefore not a complete text of biophysical or biochemical topics. The subjects chosen for discussion are related to the origin of life, the physical requirements for ordered living systems, and the physical and chemical bases for the most fundamental phenomena displayed by living systems such as photosynthesis, energy transfer and storage, and reproduction. It is hoped that this will stimulate the interest and furnish the knowledge necessary to further explore these topics in the current literature.

Designed for biology, physics, and medical students, Introductory Biophysics: Perspectives on the Living State, provides a comprehensive overview of the complex subject of biological physics. The companion CD-ROM, with MATLAB examples and the student version of QuickFieldTM, allows the student to perform biophysical simulations and modify the textbook example files. Included in the text are computer simulations of thermodynamics, astrobiology, the response of living cells to external fields, chaos in population dynamics, numerical models of evolution, electrical circuit models of cell suspension, gap junctions, and neuronal action potentials. With this text students will be able to perform biophysical simulations within hours. MATLAB examples include; the Hodgkin Huxley equations; the FitzHugh-Nagumo model of action potentials; fractal structures in biology; chaos in population dynamics; the cellular automaton model (the game of life); pattern formation in reaction-diffusion systems. QuickFieldTM tutorials and examples include; calculation of currents in biological tissue; cells under electrical stimulation; induced membrane potentials; heat transfer and analysis of stress in biomaterials.

Molecular biophysics is a rapidly growing field of research that plays an important role in elucidating the mysteries of life's molecules and their assemblies, as well as the relationship between their structure and function. Introduction to Molecular Biophysics fills an existing gap in the literature on this subject by providing the reader with th

All living matter is comprised of cells, small compartments isolated from the environment by a cell membrane and filled with concentrated solutions of various organic and inorganic compounds. Some organisms are single-cell, where all life functions are performed by that cell. Others have groups of cells, or organs, specializing in one particular function. The survival of the entire organism depends on all of its cells and organs fulfilling their roles. While the cells are studied by different sciences, they are seen differently by biologists, chemists, or physicists. Biologists concentrate their attention on cell structure and function. What the cells consists of? Where are its organelles? What function each organelle fulfils? From a chemists’ point of view, a cell is a complex chemical reaction chamber where various molecules are synthesized or degraded. The main question is how these, sometimes very complicated chains of reactions are controlled. Finally, from a physics standpoint, some of the fundamental questions are about the physical movement of all these molecules between organelles within the cell, their exchange with the extracellular medium, as well as electrical phenomena resulting from such transport. The aim of this book is to look into the basic physical phenomena occurring in cells. These physical transport processes facilitate chemical reactions in the cell and various electrical effects, and that in turn leads to biological functions necessary for the cell to satisfy its role in the mother organism. Ultimately, the goals of every cell are to stay alive and to fulfill its function as a part of a larger organ or organism. The first volume of this book is an inventory of physical transport processes occurring in cells while this second volume provides a closer look at how complex biological and physiological cell phenomena result from these very basic physical processes.

Biophysics, being an interdisciplinary topic, is of great importance in modern biology. This book addresses the needs of biologists, biochemists, and medical biophysicists for an introduction to the subject. The text is based on a one-semester course offered to graduate students of life sciences, and covers a wide range of topics from quantum mechanics to pre-biotic evolution. To understand the topics, only basic school level mathematics is required. The first chapter introduces and refreshes the reader's knowledge of physics and chemistry. The next chapters cover various physico-chemical techniques used to study biomolecular structures, followed by treatments of spectroscopy, microscopy, diffraction, and computational techniques. X-ray crystallography and NMR are dealt with in greater detail. The latter half of the book covers results obtained from applications of the above techniques. Some of the other topics dealt with are energy pathways, biomechanics, and neuro-biophysics.

This textbook provides an introduction to the fundamental and applied aspects of biophysics for advanced undergraduate and graduate students of physics, chemistry, and biology. The application of physics principles and techniques in exploring biological systems has long been a tradition in scientific research. Biological systems hold naturally inbuilt physical principles and processes which are popularly explored. Systematic discoveries help us understand the structures and functions of individual biomolecules, biomolecular systems, cells, organelles, tissues, and even the physiological systems of animals and plants. Utilizing a physics- based scientific understanding of biological systems to explore disease is at the forefront of applied scientific research. This textbook covers key breakthroughs in biophysics whilst looking ahead to future horizons and directions of research. It contains models based on both classical and quantum mechanical treatments of biological systems. It explores diseases related to physical alterations in biomolecular structures and organizations alongside drug discovery strategies. It also discusses the cutting- edge applications of nanotechnologies in manipulating nanoprocesses in biological systems. Key Features: • Presents an accessible introduction to how physics principles and techniques can be used to understand biological and biochemical systems. • Addresses natural processes, mutations, and their purposeful manipulation. • Lays the groundwork for vitally important natural scientific, technological, and medical advances.
