Current techniques for studying biological macromolecules and their interactions are based on the application of physical methods, ranging from classical thermodynamics to more recently developed techniques for the detection and manipulation of single molecules. Reflecting the advances made in biophysics research over the past decade, and now including a new section on medical imaging, this new edition describes the physical methods used in modern biology. All key techniques are covered, including mass spectrometry, hydrodynamics, microscopy and imaging, diffraction and spectroscopy, electron microscopy, molecular dynamics simulations and nuclear magnetic resonance. Each method is explained in detail using examples of real-world applications. Short asides are provided throughout to ensure that explanations are accessible to life scientists, physicists and those with medical backgrounds. The book remains an unparalleled and comprehensive resource for graduate students of biophysics and medical physics in science and medical schools, as well as for research scientists looking for an introduction to techniques from across this interdisciplinary field.

This new textbook offers a comprehensive introduction to the molecular physics of biological systems: it seeks to explain how the laws and concepts of physics apply to the living world at the molecular and subcellular level, with an emphasis on electrical and dynamical behaviour. The book is organized into five parts: * conformation of biopolymers * dynamics of biopolymers * hydration of biopolymers * biopolymers as polyelectrolytes *association between molecules The author adopts a multi-disciplinary approach and limits mathematics only to what is strictly necessary for the development of the subject. The text should be suitable for students from a wide range of backgrounds in biology, physics or chemistry taking advanced courses in molecular biophysics or biophysical chemistry.

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

Molecular Biophysics presents the fundamental principles of biophysics and their application to the study of the physical properties of biological macromolecules. The merger of biology and physics involves the development of sophisticated instrumentation and the molecular approach to the study of life phenomena. This book is composed of nine chapters and begins with an overview of the thermodynamical aspects and chemical foundations of biophysics. These topics are followed by the physical aspects of macromolecules, with a particular emphasis on the biological functions, conformation, and hydrophobic interactions of proteins. The subsequent chapter describes the structural and electro-optical properties of biopolymers based on X-ray, optical, and spectroscopic analysis. The discussion then shifts to enzymes, their chemical kinetics, catalytic potential, and conformational and cooperative properties. The remaining chapters explore the physical aspects of nucleic acids and the biosynthesis of proteins. This book will prove useful to molecular biophysicists, biologists, physicists, and researchers in the fields of life sciences.

Biophysics represents perhaps one of the best examples of interdisciplinary research areas, where concepts and methods from disciplines such as physics, biology, b- chemistry, colloid chemistry, and physiology are integrated. It is by no means a new ?eld of study and has actually been around, initially as quantitative physiology and partly as colloid science, for over a hundred years. For a long time, biophysics has been taught and practiced as a research discipline mostly in medical schools and life sciences departments, and excellent biophysics textbooks have been published that are targeted at a biologically literate audience. With a few exceptions, it is only relatively recently that biophysics has started to be recognized as a physical science and integrated into physics departments’ curr- ula, sometimes under the new name of biological physics. In this period of cryst- lization and possible rede?nition of biophysics, there still exists some uncertainty as to what biophysics might actually represent. A particular tendency among phy- cists is to associate biophysics research with the development of powerful new te- niques that should eventually be used not by physicists to study physical processes in living matter, but by biologists in their biological investigations. There is value in that judgment, and excellent books have been published that introduce the int- ested reader to the use of physical principles for the development of new methods of investigation in life sciences.

This book presents the fundamentals of molecular biophysics, and highlights the connection between molecules and biological phenomena, making it an important text across a variety of science disciplines. The topics covered in the book include: Phase transitions that occur in biosystems (protein crystallisation, globule-coil transition etc) Liquid crystallinity as an example of the delicate range of partially ordered phases found with biological molecules How molecules move and propel themselves at the cellular level The general features of self-assembly with examples from proteins The phase behaviour of DNA The physical toolbox presented within this text will form a basis for students to enter into a wide range of pure and applied bioengineering fields in medical, food and pharmaceutical areas.

This handbook describes experimental techniques to monitor and manipulate individual biomolecules, including fluorescence detection, atomic force microscopy, and optical and magnetic trapping. It includes single-molecule studies of physical properties of biomolecules such as folding, polymer physics of protein and DNA, enzymology and biochemistry, single molecules in the membrane, and single-molecule techniques in living cells.
