A lab-on-a-chip device is a microscale laboratory on a credit-card sized glass or plastic chip with a network of microchannels, electrodes, sensors and electronic circuits. These labs on a chip can duplicate the specialized functions as performed by their room-sized counterparts, such as clinical diagnoses, PCR and electrophoretic separation. The advantages of these labs on a chip include significant reduction in the amounts of samples and reagents, very short reaction and analysis time, high throughput and portability. Generally, a lab-on-a-chip device must perform a number of mic

Electrophoresis is defined as the transport of electrically charged particles in a direct current electric field. Electrophoresis has been around for more than a century as a phenomenon in electrokinetics. Field effect electroosmosis is a novel phenomenon in electrokinetics that adds a new dimension in capillary electrophoresis. In this book, field effect electroosmosis is introduced, and a beautiful spectrum of applications of electrophoresis was presented.

This title provides an overview of the innovative use of electro-kinetic phenomena in experimentally exploring non-equilibrium regions of chemically non-reacting systems. Transport phenomena mediated by charged liquid-liquid interfaces and solid-liquid interfaces are also covered. Transport phenomena mediated by electrified interfaces are discussed in the context of a number of important areas, including, soil/water systems, phase transfer catalysis, animal/plant physiology and mimicking taste/smell sensing mechanisms.- Provides an overview of the innovative use of electro-kinetic ph

The socio-economic activities due to world development are promoting increasing pressures on land, creating competition and conflicts, resulting in suboptimal use of resources. There is a need to find new strategies for sustainable development that link social and economic progress with environmental protection and enhancement. Electrokinetic transport processes (EK) uses a low-level direct current as a “cleaning agent”. EK has been applied to the remediation of polluted soils and other contaminated matrices. It also shows a great potential to be used in different fields, as in saline soil restoration, nutrients recovery from wastes or repair and maintenance of building structures. EK introduces a new integrated approach aiming at sustainable development and to support waste strategies with worldwide interest. EK can also be coupled with phytoremediation and integrated with nanotechnology, enlarging the scope of its application. The use of  EK in the recovery of secondary resources, remediation, and conservation, is a multidisciplinary and novel approach.  EK opens up new technical possibilities for waste minimization, through upgrading of particulate waste products, and the recovery of secondary resources for industrial, agricultural or social use.

Micromixers are an important component in micrototal analysis systems and lab-on-a-chip platforms which are widely used for sample preparation and analysis, drug delivery, and biological and chemical synthesis. The Special Issue "Analysis, Design and Fabrication of Micromixers II" published in Micromachines covers new mechanisms, numerical and/or experimental mixing analysis, design, and fabrication of various micromixers. This reprint includes an editorial, two review papers, and eleven research papers reporting on five active and six passive micromixers. Three of the active micromixers have electrokinetic driving force, but the other two are activated by mechanical mechanism and acoustic streaming. Three studies employs non-Newtonian working fluids, one of which deals with nano-non-Newtonian fluids. Most of the cases investigated micromixer design.
