Claim 5:
6. The microfluidic cell culture chip according to claim 1, wherein the 3D nanostructured porous membrane includes at least one layer of a polyelectrolyte selected from the group consisting of poly(sodium 4-styrenesulphonate) (PSS), poly(ethyleneimine), poly(diallyldimethylammonium chloride), poly(acrylamide-co-diallyldimethylammonium chloride), diallyldimethylammonium chloride, poly(allylamine hydrochloride) (PAH), polyanetholesulfonic acid, polyacrylic acid, poly(styrene-alt-maleic acid), polyvinyl sulphate, polyvinylsulfonic acid, poly(2-acrylamido-2-methyl-1-propanesulfonic acid), poly(2-acrylamido-2-methyl-1-propanesulfonic acid-co-acrylonitrile), poly(4-styrenesulfonic acid), poly(4-styrenesulfonic-acid-co-maleic acid), and hydrated 4-styrenesulfonic sodium salt, and
wherein when said 3D nanostructured porous membrane includes at least two successive layers, a layer consisting of a positively charged polyelectrolyte alternates with a layer consisting of a negatively charged polyelectrolyte.
