A versatile fabrication approach for the realization of complex vertical nanowire architectures on top of photolithographically patterned microscale metallic electrodes is presented (see image). Anodic aluminum oxidation combined with microfabrication and nanopatterning techniques enable site-specific electrochemical growth of nanowires inside supported nanoporous alumina templates.
