This open access book presents the most recent advances in the novel, interdisciplinary field of magnetic microhydrodynamics. This emerging area of advanced research combines magnetism with the knowledge of bioinspired local flow control to create novel concepts and technological solutions that could revolutionize the field of microfluidics. Edited and authored by world-recognized leaders in this field, this book covers how the action of magnetic forces on soft matter can result in a richness of possible static and dynamic behavior. The contributions featured in this book introduce timely examples of novel concepts (new fluids and control), processes at interfaces (local probes, electrochemistry), and applications of magnetic soft matter in cell biology, cargo transport, and energy. This book is of great interest to scientists from various backgrounds looking to explore, learn of recent developments, and take part in laying the foundations of an entirely new and dynamic field of research.
