In the twenty years since their inception, modern dynamic light-scattering techniques have become increasingly sophisticated, and their applications have grown exceedingly diverse. Applications of the techniques to problems in physics, chemistry, biology, medicine, and fluid mechanics have prolifer ated. It is probably no longer possible for one or two authors to write a monograph to cover in depth the advances in scattering techniques and the main areas in which they have made a major impact. This volume, which we expect to be the first of aseries, presents reviews of selected specialized areas by renowned experts. It makes no attempt to be comprehensive; it emphasizes a body of related applications to polymeric, biological, and colloidal systems, and to critical phenomena. The well-known monographs on dynamic light scattering by Berne and Pecora and by Chu were published almost ten years ago. They provided comprehensive treatments of the general principles of dynamic light scat tering and gave introductions to a wide variety of applications, but natu rally they could not treat the new applications and advances in older ones that have arisen in the last decade. The new applications include studies of interacting particles in solution (Chapter 4); scaling approaches to the dynamics of polymers, including polymers in semidilute solution (Chapter 5); the use of both Fabry-Perot interferometry and photon correlation spectroscopy to study bulk polymers (Chapter 6); studies of micelIes and microemulsions (Chapter 8); studies of polymer gels (Chapter 9).

Dynamic light scattering is a new method for investigating macromolecular systems. The importance of the technique lies in its non-invasive character. It can be employed on extremely small fluid volumes, the instrumentation is relatively inexpensive and allows the rapid determination of diffusion coefficients as well as providing information on relaxation time distributions for the macromolecular components of complex systems. This volume is directed in part to the philosophy and current practice in dynamic light scattering. Single photon correlation techniques are introduced; a discussion of noise on photon correlation functions is given and data analysis in dynamic light scattering to polymer structure analysis is presented; and a comprehensive introduction to diffusing wave spectroscopy is given. Theoretical developments relating dynamic light scattering to the viscoelasticity of polymers in solution and in the bulk are described. A secondary aim of the work is to illustrate the widely varying fields in which the technique finds application. Chapters address multicomponent mixtures, polyelectrolytes, dense polymer systems, gels, rigid rods, micellar systems and the application of dynamic light scattering to biological systems.

An Introduction to Dynamic Light Scattering by Macromolecules provides an introduction to the basic concepts of dynamic light scattering (DLS), with an emphasis on the interpretation of DLS data. It presents the appropriate equations used to interpret DLS data. The material is presented in order of increasing complexity of the systems under examination, ranging from dilute solutions of noninteracting particles to concentrated multicomponent solutions of strongly interacting particles and gels. Problems are presented at the end of each chapter to emphasize these concepts. Since a major emphasis of this textbook is the interpretation of DLS data obtained by polarized light scattering studies on macromolecular solutions, the results of complementary experimental techniques are also presented in order to gain insight into the dynamics of these systems. This textbook is intended for (1) advanced undergraduate students and graduate students in the chemical, physical, and biological sciences; (2) scientists who might wish to apply DLS methods to systems of interest to them but who have no formal training in the field of DLS; and (3) those who are simply curious as to the type of information that might be obtained from DLS techniques.

Light scattering is a very powerful method for characterizing the structure of polymers and nanoparticles in solution. As part of the Springer Laboratory series, this book provides a simple-to-read and illustrative textbook probing the seemingly very complicated topic of light scattering from polymers and nanoparticles in dilute solution, and goes further to cover some of the latest technical developments in experimental light scattering.

A comprehensive, practical approach to three powerful methods ofpolymer analysis and characterization This book serves as a complete compendium of three importantmethods widely used for the characterization of synthetic andnatural polymers—light scattering, size exclusionchromatography (SEC), and asymmetric flow field flow fractionation(A4F). Featuring numerous up-to-date examples of experimentalresults obtained by light scattering, SEC, and A4F measurements,Light Scattering, Size Exclusion Chromatography and Asymmetric FlowField Flow Fractionation takes an all-in-one approach to deliver acomplete and thorough explanation of the principles, theories, andinstrumentation needed to characterize polymers from the viewpointof their molar mass distribution, size, branching, and aggregation.This comprehensive resource: Is the only book gathering light scattering, size exclusionchromatography, and asymmetric flow field flow fractionation into asingle text Systematically compares results of size exclusion chromatographywith results of asymmetric flow field flow fractionation, and howthese two methods complement each other Provides in-depth guidelines for reproducible and correctdetermination of molar mass and molecular size of polymers usingSEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, andcharacterization of polymer branching Light Scattering, Size Exclusion Chromatography and AsymmetricFlow Field Flow Fractionation should be of great interest to allthose engaged in the polymer analysis and characterization inindustrial and university research, as well as in manufacturingquality control laboratories. Both beginners and experienced canconfidently rely on this volume to confirm their own understandingor to help interpret their results.
