Electrokinetics and Electrohydrodynamics in Microsystems


Book Description

Among the most promising techniques to handle small objects at the micrometer scale are those that employ electrical forces, which have the advantages of voltage-based control and dominance over other forces. The book provides a state-of-the-art knowledge on both theoretical and applied aspects of the electrical manipulation of colloidal particles and fluids in microsystems and covers the following topics: dielectrophoresis, electrowetting, electrohydrodynamics in microsystems, and electrokinetics of fluids and particles. The book is addressed to doctoral students, young or senior researchers, chemical engineers and/or biotechnologists with an interest in microfluidics, lab-on-chip or MEMS.










Micro/Nano-Chip Electrokinetics, Volume III


Book Description

Micro/nanofluidics-based lab-on-a-chip devices have found extensive applications in the analysis of chemical and biological samples over the past two decades. Electrokinetics is the method of choice in these micro/nano-chips for transporting, manipulating, and sensing various analyte species (e.g., ions, molecules, fluids, and particles). This book aims to highlight the recent developments in the field of micro/nano-chip electrokinetics, ranging from the fundamentals of electrokinetics to the applications of electrokinetics to both chemo- and bio-sample handling.




AC Electrokinetics


Book Description

Biologists, physicists and engineers are working together to make ever-smaller devices capable of studying the properties of tiny biological particles. Using nano-electrodes, encapsulated in a device with dimensions of a few hundred millionths of a metre, it is now possible to manipulate and trap single nano-scale biological particles such as a virus. The precisely controlled electric fields generated within the device can be used to trap single particles in field-cages or separate different viruses from each other, for example. This book is an introduction to the science behind the new technology, and explains how the electric field interacts with the particles. It describes how these micro-systems are manufactured and how they are used to study the electrical properties of the particles.

Nanoparticles' Promises and Risks


Book Description

The focus of this interdisciplinary volume is on four areas of nanoparticle research: characterization, manipulation, and potential effects on humanity and the environment. The book includes a comprehensive collection of data on industrial nanoparticle creation and the characterization of the nanoscale products of these processes. The authors describe the effects of these nanoscale structures on human health and discuss prospective implementations for detection and characterization of nanoparticles in the environment. They recommend, utilizing the most up-to-date understanding of nanotechnology, methods for limiting the negative effects of these products on the environment and human health through manipulation, sorting, and filtration.




Liquid Crystals


Book Description

This book on liquid crystals reports on the new perspectives that have been brought about by the recent expansion of frontiers and overhaul of common beliefs. First, it explores the interaction of light with mesophases, when the light or matter is endowed with topological defects. It goes on to show how electrophoresis, electro-osmosis and the swimming of flagellated bacteria are affected by the anisotropic properties of liquid crystals. It also reports on the recent progress in the understanding of thermomechanical and thermohydrodynamical effects in cholesterics and deformed nematics and refutes the common belief that these effects could explain Lehmann’s observations of the rotation of cholesteric droplets subjected to a temperature gradient. It then studies the physics of the dowser texture, which has remarkable properties. This is of particular interest in regards to nematic monopoles, which can easily be generated, set into motion and collided within it. Finally, this book deals with the spontaneous emergence of chirality in nematics made of achiral molecules, and provides a brief historical context of chirality




Bio-Inspired Technology


Book Description

Biomimetic devices are designed and produced by materials, structures, and systems that are modelled on biological entities and processes. These devices are used to synthesize novel materials and their functions at the multiscale level for various applications. Molecular computing biological devices play a key role in the logical processing of the cellular machinery of all living organisms. This book includes information on both biomedical and technological applications of bioactive devices for hard tissue regeneration; design of chip-based disease diagnostic platforms; neuromorphic computing biomaterials that transfer techniques of neuroscience to a silicon chip; various top-down and bottom-up designs; and electrical characterization and transport mechanisms of DNA as nanowires.
