Different modified electrodes were prepared using multi-walled carbon nanotubes (MWCNTs) prepared and purified according to different procedures. Since MWCNTs purification and functionalization is a key point for the electroanalytical performance of the final devices, MWCNTs were previously characterized from the morphological, surface and electrochemical point of view. Different parameters, such...
We propose here a quick and easy procedure for preparing pencil leads doped with Ag and AgCl suitable for the reproducible and easy drawing on paper or other porous supports of carbon based Ag/AgCl conductive lines for the use as reference electrodes. They were prepared by careful electrodeposition of silver and silver chloride on carbon powder (conductive material) which was then mixed with sodium...
