This paper deals with the problematic of microsensors for electrochemical detection of species in aqueous solutions, where the main problem is reduction of geometrical size of the electrodes in comparison to standard electrodes resulting in lower current response. In this paper there was fabricated thin film substrate of working microelectrode on silicon substrate. Direct grown deposition of multiwalled carbon nanotubes (MWCNTs) over microelectrode substrate was done using thermal CVD to increase the active size of the electrode. Electrode surface was characterized optically using scanning electron microscopy resulting in relative good and homogenous surface. Then the electrode was tested as a working electrode of three-electrode electrochemical system against standard reference and auxiliary electrode. Heavy metal ions of lead were used as analysed species for electrochemical properties characterization using differential pulse voltammetry and compared to commercial carbon based working electrode. Obtained results confirmed our presumption that direct grown MWCNTs based working electrode could be used for electrochemical analysis. The main advantage of this solution is in future possibilities of MWCNTs functionalization for bioanalysis of proteins, thiols, etc.
