“Background Nanoporous anodic alumina (NAA) is one of the smartest materials in which scientists have centered their research with considerable interest in recent years [1, 2] due to their physicochemical properties like thermal stability, environmental toughness, and biocompatibility. Alumina has been studied for decades [3]. The fabrication technology permits to obtain highly ordered and customized porous nanostructures that makes NAA very attractive for different applications such as nanomaterial synthesis [4, 5], photonics [6], or sensors [7–9]. In particular, NAA has demonstrated its sensing capabilities: a great wealth of work has been carried out with this material in biotechnology areas [10], and it presents reliable possibilities of working as portable chemical and biochemical sensors [11], as well as label-free biosensors [12]. Furthermore, if the optical waveguide properties of NAA are exploited, much higher sensitivities than conventional surface plasmon resonance (SPR) sensors [2, 13, 14] can be achieved. Sensors based on alumina improve their sensitivity by the measurement of the oscillations in the reflectance spectrum produced by the Fabry-Pérot (F-P) interferences in a NAA thin film [15, 16].
