Original Abstract

The aim of this work is the optimization and following characterization of gold nanostructured electrochemical sensors suitable for biomolecules and heavy metal ion detection. Gold nanoparticles need to be examined for biocompatibility and environmental impacts. The EIS (electrochemical impedance spectroscopy) measurements of surfaces with various nanoparticles geometry have shown a strong dependence of active electrochemical surfaces area on the rate of nanomachining. The main aim of the paper presented is discovery of planar nanostructured electrode with selected size of nanoparticles which can bring greater benefit in their application in biochemistry in comparison to a flat gold electrode. The cyclic voltammetry method has prooved that nanowires with selected aspect ratio have increased electrochemicaly active area of electrodes.
