1. Illustration of electrophoresis. 2. Illustration of electrophoresis retardation. In chemistry, electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field. As a rule, these are zwitterions.

Iontophoresis is a process of transdermal drug delivery by use of a voltage gradient on the skin. [1] [2] Molecules are transported across the stratum corneum by electrophoresis and electroosmosis and the electric field can also increase the permeability of the skin.
Mechanisms of action. While increased skin permeability is seen through sonophoresis, the precise mechanisms to describe sonophoresis are yet to be fully discovered. However, there are several important mechanisms that have been identified that contribute to the phenomenon of sonophoresis.
Notable minority language (less than 25% but more than 500,000 Spanish speakers) Spanish is the primary language in 20 countries worldwide. As of 2023, it is estimated that about 486 million people speak Spanish as a native language, making it the second most spoken language by number of native speakers. [29]
