Opis

Dynamic light scattering (DLS) is an important concept that has found applications in the characterization of the biophysical properties of materials for a wide range of applications. DLS studies are extensively employed in material science and engineering to evaluate particle size distribution and surface charge for applications in nanomaterial synthesis, biomolecular analysis, pharmaceutical development and environmental applications. The aim of this book is to provide an overview of research advances relating to the principle and applications of DLS in various fields. The book is divided into two parts a Part 1 discusses the uses of DLS in material science and engineering applications and Part 2 focuses on applications of DLS in biological sciences. Chapter 1aDLS Studies: Recent Trends in Characterizationaaims to provide an overview of the working principle, mathematical models and different types of DLS analysis methods. In addition, recent trends in DLS studies and applications in various fields are also discussed. Chapter 2aApplication of DLS Technique in Nanomaterial Characterizationadiscusses the uses of DLS for nanomaterial characterization in terms of the size, size distribution and zeta potential of particles. Chapter 3aPotentialities of DLS with SAXS Studies to Analyze Heterogenous Nanocatalysta compares two techniques (DLS and SAXS) and provides evidence that nanocatalyst can be characterized more effectively by modifying DLS with SAXS. In Chapter 4aDLS Studies on Self-Assembling Copolymer Nanostructuresathe authors demonstrate the application of DLS in characterizing self-assembling and stimuli-responsive di-block copolymers in aqueous media and their association with low molecular weight drugs. Chapter 5a Slow and Ultraslow Relaxations in Molecular and Ionic Liquids-based Unary and Binary Systemsadiscusses slow and ultraslow dynamics, probed by DLS measurements, in common organic molecular liquids, ionic liquids (ILs), aqueous solutions of salts and molecular solids and liquid-liquid binary mixtures. In part 2, Chapter 6aApplications of DLS Studies in Phytochemical Analysisa discusses the application of dynamic light scattering for particle size determination using natural phytochemicals derived from plants. Chapter 7aApplications of DLS in Pharmaceutical Industrya is a comprehensive review of DLS analysis in pharmaceutical research, development and production. Chapter 8aDLS Studies of the Protein-Surfactant Systemadiscusses the relationship between viscosity and DLS measurement using the growth behavior of SDS micelle. The authors ofaChapter 9aApplications of DLS Studies in Microbial Surface Charge Analysisaprovides an overview of the wider applications of DLS studies in evaluating the surface charge of microbes via zeta potential analysis. Additionally, the mechanisms of microbial surface charge in elevating their growth rate is also discussed. The final chapteraOverview and Future Perspective of DLS Studiesais a brief summary of the application of DLS analysis in various fields and the relevant considerations for DLS analysis in particle characterization. In addition, hybrid instrumentation and DLS coupling with other techniques are discussed. We hope that this book will help to enlighten undergraduates and graduates research students as well as early and seasoned researchers on advances in DLS techniques and emerging applications.
