Aquaporin-based membranes

Definition

Aquaporin-based membranes are specialized filtration membranes that utilize aquaporins, which are integral membrane proteins that facilitate the rapid transport of water molecules across cell membranes. These membranes mimic natural biological systems, enhancing water permeability while selectively filtering solutes. By incorporating aquaporins into synthetic or biomimetic membranes, researchers aim to create highly efficient systems for water treatment and desalination, leveraging the unique properties of these proteins.
