The aim of this paper is to show the possibilities of heavy metals electrochemical detection on direct grown multiwalled carbon nanotubes (MWNTs) based microelectrode. The electrode substrate was fabricated using standard lithography and thin film technology on silicon substrate. The working electrode (WE) deposition in a form of vertically aligned MWNTs was done on the electrode substrate using CVD. Fabricated electrodes were tested optically using scanning electron microscopy with good result and electrochemically using electrochemical detection of lead ions in acetate buffer solution. The electrochemical measurement confirmed the suitability of fabricated electrode for lead with the detection limit of 3 umol/L. Finally the comparison of fabricated WE with the WE from commercial electrochemical based on carbon nanotubes (CNTs) have been done resulting in almost two times better sensitivity of our electrode.
