The potential of polymeric nanostructures obtained by extruding polymer solutions through reusable anodic aluminum oxide (AAO) nanopores for the fabrication is investigated systematically to be able unveil impact structure on cell culturing. Thus, nanostructured Na-alginate and poly(vinyl alcohol) (PVA) polymers as well blended alginate/PVA hydrogels are fabricated. PVA fibers with different di...
