Cataphoresis vs. Anaphoresis — What's the Difference?
By Tayyaba Rehman — Updated on November 3, 2023
Cataphoresis involves particles moving toward a cathode in a fluid medium, while anaphoresis refers to the movement toward an anode.

Key Differences
Cataphoresis is a process where negatively charged particles move towards a positively charged electrode, known as a cathode, within a fluid under the influence of an electric field. Anaphoresis, on the contrary, involves positively charged particles migrating towards a negatively charged electrode, the anode.
In cataphoresis, the motion of particles towards the cathode is facilitated by the electrical potential, often used in industrial coatings. Anaphoresis often describes the movement in electrophoresis where particles are driven by electrical potential across a medium towards the anode.
The term cataphoresis can also be applied in medicine, where it is used for therapeutic and drug delivery purposes, by moving substances across the skin. Meanwhile, anaphoresis is not commonly referenced in medical contexts but is a critical part of the separation processes in chemistry and biology.
One could see cataphoresis as a specific type of electrophoresis. Anaphoresis, although less commonly used, is a term that complements cataphoresis in the description of particle movements in an electric field, helping to provide a full picture of the directional movement possibilities.
While cataphoresis is mostly associated with coatings and medicinal applications, the principle behind it serves various industrial processes. Anaphoresis is typically discussed in analytical and preparative processes, particularly in biochemistry for the separation of molecules.

Cataphoresis
Cataphoresis involves the application of DC current to drive substances across the skin.
The medication was administered through cataphoresis for deeper skin penetration.
Anaphoresis
Anaphoresis is used in biochemistry for the separation of molecules by their charge.
Anaphoresis allowed for the precise isolation of the desired cellular components.
Cataphoresis
Cataphoresis is the movement of particles toward a cathode in a fluid medium.
Cataphoresis was used to apply the paint evenly across the metal surface.
Anaphoresis
Anaphoresis is the migration of particles toward an anode in an electrolyte solution.
Anaphoresis was observed during the electrophoretic experiment in the lab.
Cataphoresis
It is a technique for coating objects by attracting negatively charged particles to a surface.
The cataphoresis process resulted in a durable and even protective layer on the car parts.
Anaphoresis
In anaphoresis, particles are drawn to a negative electrode due to electrical potential.
The anaphoresis process ensured the collection of ions at the anode.
Cataphoresis
Cataphoresis can be a medical procedure for ionic drug transport.
The patient underwent cataphoresis for targeted drug delivery.
Anaphoresis
It can describe the electrokinetic phenomenon in an opposite manner to cataphoresis.
Contrary to cataphoresis, anaphoresis was responsible for the attraction of cations in the solution.
Cataphoresis
In cataphoresis, particles migrate in response to an electric field towards a positive electrode.
Cataphoresis was critical in the experiment to ensure the particles adhered to the substrate.
Anaphoresis
It refers to the movement of positively charged colloids under the influence of an electric field.
Scientists used anaphoresis to separate various proteins for analysis.
