Molecular and Colloidal Electro-Optics presents a well-integrated yet multi-disciplinary treatment of fundamental principles, strategies, and applications of electro-optic techniques for the characterization of macromolecular, small-particle, and nanomolecular systems. The book highlights the latest achievements in electro-optic theory, particularly low-frequency relaxation, and the unique advantage of using electro-optics as an alternative to conventional characterization and analysis of colloidal systems. As the first treatment of this subject to surface in more than fifteen years, this book is a definitive, up-to-date portrait of modern colloidal electro-optic science that is ideal for advanced graduate students and researchers in biophysical chemistry, microbiology, polymer, colloid, and nanoscience.
