An electrical double layer (EDL) may appear at the interface between a fluid and an object (a solid or another immiscible fluid) in contact with each other. Upon the application of an electric field to this system, ions can experience an electromagnetic force, inducing fluid flow (e.g., electroosmotic flow) or causing particles suspended within the fluid to migrate (e.g., electrophoresis). Electrokinetics is the discipline that addresses these phenomena and is a commonly utilized method for the manipulation of particles and fluids at the micro-to-nanometer scale.
Furthermore, when an electric potential is applied to electrodes submerged in a fluid, an electrical double layer forms on the electrode surfaces, leading to a phenomenon known as electrode polarization. This phenomenon not only profoundly impacts the monitoring and detection of biochemical reactions through electrical means but also generates various forms of fluid motion.
This course will cover the fundamental theories and knowledge of the electrical double layer and electrokinetics.
