Molecular biophysics is an interdisciplinary domain of research which combines the principles of physics, chemistry, mathematics, engineering and biology. It aims to explain bimolecular systems and biological functions in terms of dynamic behaviour, molecular structure and structural organization. This field seeks to understand biological processes and functions at different levels of complexity, such as from viruses to small living systems, and from single molecules to supramolecular structures. The study of allosteric interactions, molecular forces, molecular associations, cable theory and Brownian motion are also addressed by molecular biophysics. Procedures that enable imaging and manipulation of living structures aid research in molecular biophysics. Spectroscopic techniques comprising of laser Raman, FT-NMR, FT-infrared, spin label electron spin resonance, etc. are widely used to understand structural dynamics of biomolecules and their intermolecular interactions. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of molecular biophysics. The various advancements in this field are glanced at and their applications as well as ramifications are looked at in detail. Students, researchers, experts and all associated with molecular biophysics will benefit alike from this book.
