“…Template-assisted formation of metallic nanowires employs mainly electrochemical methods. However, one can find barely few others like surface redox reaction (cementation) [197], vacuum evaporation (DC sputtering) [153], solid state reduction [63], or pressure casting [16].…”

Anodic aluminum oxide (AAO) consists of parallel pores arranged in a honeycomb-like array. Since a two-step self-organized approach in anodic alumina fabrication was invented, tremendous attention was paid to this material. Structural features of anodic alumina, like pore diameter, interpore distance, and nanoporous oxide thickness, can be fully controlled by operating conditions, including type, concentration and temperature of the electrolyte, applied voltage, and duration of the anodization process. Moreover, these operating conditions have also a major impact on the nanoporous array arrangement. Quantitative arrangement analysis methods employing fast Fourier transforms have been developed to assess the nanopores' arrangement. The most frequent application of the anodic aluminum oxide is a template-assisted fabrication of nanostructures. Templates made of the AAO are being successfully applied in fabrication of nanowires, nanotubes, and nanodots by using diversity of techniques, including electrochemical deposition, physical and chemical vapor deposition, sol-gel techniques, etc. Due to the size of obtained nanostructures, magnetic, electric, piezoelectric, luminescent, and catalytic properties of the deposited materials can be significantly improved. Thus, control of the nanopores' structural features and arrangement is crucial for AAO applications in nanotechnology.

“…Unlike track-etch membranes, the pores in the AAO membrane are almost parallel to the surface normal. Typical membrane thickness is up to 100 μm but more limited in pore sizes compared to PCTE (Foss et al, 1992, 1994; Pang et al, 2002, 2003a,b,c; Tian et al, 2004). …”

Nanoscale structures have been at the core of research efforts dealing with integration of nanotechnology into novel electronic devices for the last decade. Because the size of nanomaterials is of the same order of magnitude as biomolecules, these materials are valuable tools for nanoscale manipulation in a broad range of neurobiological systems. For instance, the unique electrical and optical properties of nanowires, nanotubes, and nanocables with vertical orientation, assembled in nanoscale arrays, have been used in many device applications such as sensors that hold the potential to augment brain functions. However, the challenge in creating nanowires/nanotubes or nanocables array-based sensors lies in making individual electrical connections fitting both the features of the brain and of the nanostructures. This review discusses two of the most important applications of nanostructures in neuroscience. First, the current approaches to create nanowires and nanocable structures are reviewed to critically evaluate their potential for developing unique nanostructure based sensors to improve recording and device performance to reduce noise and the detrimental effect of the interface on the tissue. Second, the implementation of nanomaterials in neurobiological and medical applications will be considered from the brain augmentation perspective. Novel applications for diagnosis and treatment of brain diseases such as multiple sclerosis, meningitis, stroke, epilepsy, Alzheimer's disease, schizophrenia, and autism will be considered. Because the blood brain barrier (BBB) has a defensive mechanism in preventing nanomaterials arrival to the brain, various strategies to help them to pass through the BBB will be discussed. Finally, the implementation of nanomaterials in neurobiological applications is addressed from the brain repair/augmentation perspective. These nanostructures at the interface between nanotechnology and neuroscience will play a pivotal role not only in addressing the multitude of brain disorders but also to repair or augment brain functions.
