(Irregular plural: electrophoreses)
The motion of charged particles in a colloid under the influence of an electric field; particles with a positive charge go to the cathode and negative to the anode; SYN. cataphoresis.
The diffusion of charged particles through a fluid under the influence of an electric field. It can be used in the biological sciences to separate molecules of different sizes, which diffuse at different rates. In industry, electrophoresis is used in paint-dipping operations to ensure that paint reaches awkward corners.
