A macromolecule membrane structure ( 2 ) comprises a membrane ( 3 ) with water-channeling integral membrane proteins (IMPS) ( 1 ) and is coated, on a first surface, with a silica layer ( 4 ). The silica layer ( 4 ) stabilizes the macromolecule membrane structure ( 2 ) and the water-channeling IMPS ( 1 ) while maintaining the water-channeling function of the water-channeling IMPs ( 1 ). As a consequence of this stabilization, the macromolecule membrane structure ( 2 ) may be used in a filtration device ( 5 ) for various filtration operations, including water purification. |
