Central values obtained incautiously from this representation often lead to significant interpretation errors. We address the misleading way DLS size distributions are often presented, that is, as a logarithmically scaled histogram of measured relative quantities. Here, we critically discuss the application of DLS for nanoparticle characterization and provide much-needed clarification for ambiguities in the mean-value practice of commercial DLS software and documentary standards. Chapters are to be found on multicomponent mixtures, polyelectrolytes, dense polymer systems, gels, rigid rods, micellar systems and the application of dynamic light scattering to biological systems.ġ:Dynamic scattering from multicomponent polymer mixtures in solution and in bulkģ:Noise on photon correlation functions and its effects on data reduction algorithmsĤ:Data analysis in dynamic light scatteringĥ:Dynamic light scattering and linear viscoelasticity of polymers in solution and in the bulkĦ:Dynamic properties of polymer solutionsħ:Application of dynamic light scattering to polyelectrolytes in solutionĨ:Simultaneous static and dynamic light scattering: application to polymer structure analysisĩ:Dynamic light scattering from dense polymer systemsġ0:Dynamic light scattering from polymers in solution and in bulkġ1:Dynamic light scattering from polymer gelsġ2:Dynamic light scattering from rigid and nearly rigid rodsġ4:Critical dynamics of binary liquid mixtures and simple fluids studied using dynamic light scatteringġ5:Application of dynamic light scattering to biological systemsDynamic light scattering (DLS) is an essential technique for nanoparticle size analysis and has been employed extensively for decades, but despite its long history and popularity, the choice of weighting and mean of the size distribution often appears to be picked ad hoc to bring the results into agreement with other methods and expectations by any means necessary. The second aim is to illustrate the widely varying fields in which the technique finds application. Theoretical developments relating dynamic light scattering to the viscoelasticity of polymers in solution and in the bulk are described. 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. 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. The importance of the technique lies in its non-invasive character.
