Original Abstract
The purpose of this work is to characterize the nanostructured electrochemical sensors composed of ordered gold nanowires array. Noble metals, especially, gold, are very suitable for biological applications in the field of fragment DNA detection. In this case, the EIS (electrochemical impedance spectroscopy) is usually used for surface characterization and following DNA detection. Moreover, the EIS has showed the high dependence between the rate of nanomachining and active electrochemical surface area, which is directly related to the level of sensitivity. The present paper also deals with the fabrication of nanoporous anodic aluminium oxide (AAO) for thin film applications. Namely, AAO has been used as a template for the growth of various functional nanomaterials and as a scaffold for nanodevices and systems. A new electrochemical approach of pore opening from AAO bottom, i. e. selective perforation of oxide barrier on AAO bottom using re-anodization technique was developed. The skip phasing of oxide barriers wet etching is the significant advantage of re-anodization compared to other techniques for AAO, since it does not cause the widening of the naturally grown pore size. The dissolution of oxide barrier is carried out in the same acid as the anodization process and the perforation is controlled only by current density and applied voltage
