Nature-inspired synthetic membranes could aid water purification, energy, and healthcare needs
Materials scientists have created a new material that performs like a cell membrane found in nature. Such a material has long been sought for applications as varied as water purification and drug delivery.
Referred to as a lipid-like peptoid (we’ll unpack that in a second), the material can assemble itself into a sheet thinner, but more stable, than a soap bubble, the researchers report this week in Nature Communications. The assembled sheet can withstand being submerged in a variety of liquids and can even repair itself after damage.
“Nature is very smart. Researchers are trying to make biomimetic membranes that are stable and have certain desired properties of cell membranes,” said chemist Chun-Long Chen at the Department of Energy’s Pacific Northwest National Laboratory. “We believe these materials have potential in water filters, sensors, drug delivery and especially fuel cells or other energy applications.”
