dc.description.abstract	Gold nanoparticles protected with a mixture of hexanothiol and MUA (11-mercaptoundecanoic acid) (AuNP1) were reacted with Co(II) tetraaminophtalocyanine (CoTAPc). The resulting nanoparticles formed via covalent bonds, AuNP2, were characterized by absorption spectra, infrared spectroscopy and transmission electron microscopy. Modified carbon paste electrodes were prepared with AuNP1, CoTAPc and AuNP2 and evaluated for electrochemical detection of L-cysteine by cyclic voltammetry. Sensing of L-cysteine was uniquely observed with the electrode modified with AuNP2
