Abstract
In the first part, a summary of the design, the assembly, and the structural and functional characterization of nanostructured materials using anodized aluminum oxide (AAO) as a template is described. A particularly powerful analytical tool is optical waveguide spectroscopy using the nanoporous template as the guiding structure. It is demonstrated that this format allows for a very sensitive label-free detection of analytes of low molecular mass. Other strategies for using the AAO layers as templates include the growth of polymeric nano-rod arrays from different functional monomers which after the dissolution of the template are still able to guide light. This opens up novel concepts for integrated optics platforms with nanostructured materials. In the second part, we introduce an electronic transducer principle based on graphene field effect transistors that allow us to monitor enzymatic activities of multilayer assemblies by this novel analytical approach.
