The present invention provides a metal electrode stabilised by a coating, the coating comprising a sulfur containing moiety in its molecular structure. The coating may also include a hydrophilic group and a spacer between the sulfur containing moiety and the hydrophilic group. Preferably, the sulphur-containing moiety is selected from the group comprising thiol, disulphide and SO x, and the hydrophilic group is selected from the group comprising hydroxyl, amine, carboxyl, carbonyl, oligo (ethylene oxide) chain, and zwitterionic species. Compounds useful in the present invention include 2- mercaptoethanol, 2-mercaptoethylamine, 3-mercaptopropionic acid, thiophene, 4-carboxythiophene, cysteine, homocysteine, and cystine.
Electrode métallique stabilisée par un revêtement qui comporte une fraction contenant du soufre dans sa structure moléculaire. Ledit revêtement peut également posséder un groupe hydrophile et un espaceur placé entre la fraction contenant le soufre et le groupe hydrophile. De préférence, la fraction contenant le soufre est choisie dans le groupe comprenant thiol, disulfure et SOx et le groupe hydrophile est choisi dans le groupe constitué par hydroxyle, amine, carboxyle, carbonyle, chaîne oligo (oxyde d'éthylène) et des espèces zwittérioniques. Des composés utiles selon la présente invention sont 2-mercaptoéthanol, 2-mercaptoéthylamine, acide 3-mercaptopropionique, thiophène, 4-carboxythiophène, cystéine, homocystéine et cystine.
