In the last years structurally engineered nanoporous materials have attracted an increasing interest due to their potential applications in different research fields such as nanophotonic, biotechnology, sensing, catalysis, drug delivery, tissue engineering, batteries, membrane separation, and so on. Among other, nanoporous anodic alumina (NAA) has become an interesting material as a result of their outstanding set of properties, cost-competitive fabrication processes and fully scalable process compatible with conventional micro- and nanofabrication technology.
