FAQ
Frequently Asked Questions
Electrophoresis is the general term for the movement of charged particles in a fluid under an electric field. Cataphoresis specifically refers to the movement of positively charged particles (or negatively charged particles in a reversed system) towards the cathode. It is thus a subtype of electrophoresis.
Yes, but the term 'iontophoresis' is more common in modern medical contexts. The principle of cataphoresis (using electric current to drive positively charged drug ions into the body) is used in some transdermal drug delivery systems and physiotherapy treatments.
It is a highly specialised scientific term. In most general scientific and educational contexts, the broader, more familiar term 'electrophoresis' is preferred. 'Cataphoresis' is typically used only when specifying direction of movement relative to the cathode is crucial.
The direct antonym is 'anaphoresis', which is the movement of charged particles towards the anode under the influence of an electric field.
The movement of charged particles, especially colloidal particles, through a fluid under the influence of an electric field, towards the cathode.
Cataphoresis is usually highly technical/scientific in register.
Cataphoresis: in British English it is pronounced /ˌkatəfəˈriːsɪs/, and in American English it is pronounced /ˌkædəfəˈrisɪs/. Tap the audio buttons above to hear it.

Mnemonic
Think: A CAT was PHORed (forced) by an E-SIS (electric system) to move towards the CAT-hode. Cat + a + phoresis (like 'phoresis' in electrophoresis).
Conceptual Metaphor
MOVEMENT IS A JOURNEY TOWARDS A GOAL (the cathode). ELECTRICITY IS A FORCE.
