Large area nanopatterning by combined Anodic Aluminum Oxide and soft UV-NIL technologies for applications in biology

Abstract : Combining the nanoporous anodic aluminum oxide (AAO) technique with soft lithography constitutes a highly reproducible and quick method for large-area nanopatterning, with increasing potential for applications in biology. The AAO templates were used as master-molds to fabricate large areas (several square centimeters) of nanostructured and ordered tapered PDMS-bumps. The master-molds were filled using hexane-diluted PDMS of reduced viscosity compared to standard one. Viscosity evolution study for different current agent and hexane concentrations was achieved. The as-obtained stamps served subsequently to create large-area highly ordered nanostructured silicon substrates using UV assisted Nanoimprint Lithography (UV–NIL).
