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 a an urgent need for a text that provides students with the modern theoretical tools they need to understand life processes from a physical viewpoint. The authors use a combination of biological information with physical models and theories to provide a rigorous description of biological structures. The theme throughout Introduction to Molecular Biophysics is the hierarchical organization of all living systems starting with single cells and building up to systems and organisms.
