Definition

Noun: 1. 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. This is a scientific term describing a specific type of electromigration, often used in chemistry and biology.

Usage

• Cataphoresis is a technical term used primarily in scientific contexts, such as physical chemistry, biochemistry, and industrial processes. It describes the core principle behind techniques for separating molecules based on their charge and size.

Examples

• Noun:
  • The separation of proteins in the gel was achieved through cataphoresis.
  • Researchers used cataphoresis to study the migration of colloidal particles.

Advanced Usage

• "Zone cataphoresis": A refinement of the technique where separation occurs in a stabilizing medium, like a gel or paper strip, to prevent mixing.
  • Zone cataphoresis provides better resolution for analyzing complex protein mixtures.

Variants and Related Words

• Electrophoresis (n): A more common, general synonym for cataphoresis. While often used interchangeably, "cataphoresis" can specifically refer to the migration of positively charged particles (cations).
• Cataphoretic (adj): Relating to or involving cataphoresis.
  • The cataphoretic coating process deposits paint onto a metal surface.

Synonyms

• Electrophoresis: The movement of dispersed particles relative to a fluid under the influence of a spatially uniform electric field.
• Ionophoresis: The movement of ions under the influence of an electric field.

Noun

1. 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
