Proof of Water Wires Motivated by a Biological Water Channel
Aquaporins are proteins that serve as water channels to regulate the flow of water across biological cell membranes. They also remove excess salt and impurities in the body, and it is this aspect that has led to much interest in recent years in how to mimic the biochemical processes of aquaporins potentially for water desalination systems. An international team of researchers co-led by Georges Belfort has discovered water, in the form of “water wires,” contained in another molecule—the imidazole—a nitrogen-based organic compound that could be used as a potential building block for artificial aquaporins. The findings were recently published in Science Advances by the American Association for the Advancement of Science. Belfort is Institute Professor and professor of chemical and biological engineering at Rensselaer Polytechnic Institute.
