Relating to the movement of liquid through a porous material when an electric field is applied.
The electroosmotic effect is used in various scientific applications to control fluid movement.
Electroosmotic → It is formed from "electro-" (from Greek "ēlektron", meaning amber or electricity) and "osmotic" (from Greek "osmos", meaning push or thrust). The term describes the movement of water through a membrane under the influence of an electric field, highlighting the role of electricity in the osmotic process.
Think of 'electricity' ('electro-') pushing water through a barrier ('osmotic') — that's what electroosmotic means.
