Original Abstract

Nanoporous alumina is useful material for development of electrochemical sensors including filtration, molecule sorting and subsequent detection. Big advantage of alumina is possibility to reliably control size of nanopores and membrane thickness. For sensorial utilization, it is necessary to know diffusion properties of membranes and their permeability of various substances. Therefore, membranes with different pore diameter and thickness were prepared by two step anodization and modified by deposition of gold layers which serve as electrodes. Thereafter, their influence on changes of electrochemical impedance spectra was studied and compared in dependency on membrane morphology.
