Artificial Water Channels: Towards Biomimetic Membranes for Desalination

Chemistry. 2021 Feb 1;27(7):2224-2239. doi: 10.1002/chem.202003470. Epub 2020 Nov 30.

Abstract

Natural Aquaporin (AQP) channels are efficient water translocating proteins, rejecting ions. Inspired by this masterpiece of nature, Artificial Water Channels (AWCs) with controlled functional structures, can be potentially used to mimic the AQPs to a certain extent, offering flexible avenues toward biomimetic membranes for water purification. The objective of this paper is to trace the historical development and significant advancements of current reported AWCs. Meanwhile, we attempt to reveal important structural insights and supramolecular self-assembly principles governing the selective water transport mechanisms, toward innovative AWC-based biomimetic membranes for desalination.

Keywords: bilayer membranes; biomimetic; desalination; self-assembly; water channels.
