Monoclinic Ag₂S and Ag₂S/Cu₂S crystals have been synthesized by the hydrothermal decomposition of Ag or Ag/Cu diethyldithiocarbamate complex obtained by mixing sodium diethyldithiocarbamate, Ag₂SO₄ and CuCl₂ in absolute ethanol. Ag₂S and Ag₂S/Cu₂S crystals with the microscale size exhibit irregular morphology. The electrochemical responses of Ag₂S and Ag₂S/Cu₂S crystal modified glassy carbon electrode in KCl and pbs solution show the semi-reversible electrochemical process, which may originate from cysteine. The Ag₂S and Ag₂S/Cu₂S crystal modified electrodes are considered to exhibit great potential to be used as the electrochemical sensors for detecting cysteine. [DOI: 10.1380/ejssnt.2010.384]
