Nanoparticles and their ordered arrays have many important applications in fields such as electronic, optical, memory storage devices and sensors. Herein, a simple method was used for fabricating three-dimensional ordered gold nanoparticle arrays with template technique. Gold films were deposited onto anodic aluminum oxide by using electron beam evaporation. After thermal annealing, interestingly, order arrays of gold nanoparticles were obtained by a thermodynamically driven self-assembled process. The spectrum taken by UV-Vis spectrophotometer demonstrates clear surface plasmon resonance at around 500 nm, which appears blue-shift compared with usual gold nanoparticles.

In this paper, a simple, efficient and environmental friendly method was proposed to fabricate TiO2/CdS nanotube arrays. The composite nanotubes with a core-shell coaxial structure were fabricated via a simple method of liquid deposition and double diffusion using anodic aluminum oxide (AAO) templates. The photocatalytic properties of the nanotube arrays (TiO2, TiO2/CdS) were confirmed by the degradation of methyl orange (MO) under UV irradiation. Compared to bare TiO2 nanotube arrays, TiO2/CdS composite nanotube arrays showed improved photocatalytic performance: The degradation efficiency of TiO2/CdS and TiO2 nanotube arrays towards methyl orange was 65% and 39%, respectively.

Nanoporous anodic aluminum oxide (AAO) internalized with gold nanoparticles was utilized as an integrated platform miniaturized for consecutively performing on-chip PCR and downstream detection of the target DNA amplicons using surface-enhanced Raman scattering (SERS).

In this paper a simple method is used for fabrication of vertically aligned carbon nanotube (VACNT) within the cylindrical pores anodic aluminum oxide (AAO) substrate. Electronic and mechanical properties of VACNT have been obtained after removing AAO substrate. Vertically aligned carbon nanotube shows very interesting electromechanical properties which can be used in CNT-based sensors to detect chemical analytical or physical properties such as temperature orpressure.
