摘要

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