Original Abstract

The creation of an indented surface is essential for an effective enlargement of the active area of microsensors. The enlargement of electrodes leads to a significant increase in the microsensor sensitivity and signal response. The enlargement can be accomplished in a number of ways but the most simple and low-cost technology is the template-based electrodeposition method. The method consists of two phases. At first, the Al2O3 template is made by anodic oxidation, which the nanostructures are formed through and then the nanostructure formation by galvanic and chemical deposition. Electrodeposition repose on the metal deposition on the conductive substrate (representing cathode) leaving the insulant Al2O3 template. After that the template dissolved in a suitable dissolvent (e.g. NaOH) the nanostructured surface is obtained.
