Abstract
The quick development in nanotechnology has raised the status of this
modern technology owing to the decrease in the sizes of structures and devices. There
has been considerable dispute concerning the future consequences of nanotechnology.
Nanotechnology has the probable ability to design many new and novel materials and
devices in smaller dimensions with broad-range applications in medicine, electronics
and sustainable energy production. Nano porous anodic aluminum oxide (AAO) films
consisting of self-organized hexagonal arrays of invariable parallel nanochannels have
been widely applied as the building block to fabricate various functional nanostructures
of different morphologies such as nanoparticles, nanowires and nanotubes. These
functional nanostructures can be potentially utilized in various applications like
magnetic storage media, optoelectronics, bio/chemical sensors, photonics and
plasmonics. This chapter describes the different fabrication processes of AAO films in
detail along with citation of a few interesting applications.
