Referring to or relating to electrophoresis, an electrochemical process in which colloidal particles or macromolecules with a net electric charge migrate in a solution under the influence of an electric current.

A process used to apply the first coat of paint (primer) on the bodies of cars.

The process involves using negatively charged paint particles (anodic electropainting) or positively charged paint particles (cathodic electropainting).

The cleaned metal parts to be coated are immersed in a tank of electrodeposition paint, and the current is turned on, so that the paint particles are attracted by the positively charged paint particles.

1. A surface coating on a metal deposited by electric discharge of particles from a colloidal solution.
2. A term for a broad range of industrial processes including colloidal particles suspended in a liquid medium that migrate under the influence of an electric field (electrophoresis) and which are deposited onto an electrode.

All colloidal particles that can be used to form stable suspensions and which can carry a charge, can be used in electrophoretic deposition. This includes materials such as polymers, pigments, dyes, ceramics and metals.

1. A display that forms visible images by rearranging charged pigment particles using an applied electric field.
2. A liquid crystal display in which a light-absorbing dye has been added to the liquid to improve both color and luminance contrast.

Individual electrically charged dye particles move when an electric field is applied.

3. A reflective display which offers a wide choice of colors and has a short-to-medium-term memory which consumes no power.

The heart of the display is a suspension of charge pigment particles in a liquid of another color.

The suspension, a layer typically 50 micrometers thick, is sandwiched between a pair of electrodes, one of which is transparent.

When direct current of the right polarity is applied to the electrodes, the particles are pulled toward the transparent electrode thus displacing the contrasting liquid and showing their own coloration.

1. The tendency of an applied electromotive force to move an ionic atmosphere in a direction opposite to that of the motion of the central ion, creating a counter-current effect which reduces the ion's velocity.
2. A retarding effect on the characteristic motion of an ion in an electrolytic solution subjected to a potential gradient, that results from a motion in the opposite direction by the ion atmosphere.

1. The tendency of cells or compounds in a solution to move in an electric field toward an positive or negative electrode.
2. A characteristic of living cells in suspension (a dispersion of fine solid or liquid particles in a fluid) and biological compounds (proteins) in a solution to travel in an electric field to the positive or negative electrode, because of the charge on these substances.

1. Proteins which can be divided into distinct electrophoretic components because of the variations in their mobilities.
2. Physical and biochemical characteristics of an organism as determined by the interaction of its genetic constitution and the environment of the different proteins which are separable into distinct electrophoretic components because of the differences in mobilities.

One example is erythrocyte acid phosphatase.

The term erythrocyte refers to a blood cell that carries oxygen from the lungs to the body tissues; while, the term phosphatase is an enzyme that catalyzes the hydrolysis and synthesis of phosphoric acid esters (organic compounds that can react with water to produce an alcohol and an organic or inorganic acid) and the transfer of phosphate groups from phosphoric acid to other compounds.

1. The rate at which charged particles move in a solution under the influence of an electric field.
2. The velocity of a charged particle during electrophoresis.

It is normally proportional to an electric field of strength.
