Researchers in Saudi Arabia at King Abdullah University of Science & Technology have created a membrane comprising a thin layer of densely packed, highly ordered cylindrical channels with uniform pore sizes - oriented perpendicular to its surface - on top of a non-ordered sponge-like layer. It is fabricated in a fast, one-step process by combining the self-assembly of an amphiphilic block copolymer (PS- b-P4VP) with non-solvent-induced phase separation. The university's "Seed Fund" has helped the researchers to start manufacturing this membrane, which is particularly suited to size-selective and charge-based separation of bio-molecules. © 2013 Elsevier Ltd.
