Technology
A team led by scientists from the Department of Biological Sciences of the National University of Singapore (NUS) in collaboration with the French Center for Scientific Research (CNRS) has successfully synthesized a special protein mimetic that can self-assemble into a porous structure. When embedded in a lipid membrane, pores allow selective transport of water across the membrane while rejecting salt (ions). These protein mimics, known as “oligourea foldamers”, represent an entirely new class of artificial water channels (AWCs) that can be used to improve the energy efficiency of current industrial water purification methods:
