Abstract: It was found out that 8-mercaptoquinoline (MQ) could form very compact and even self-assembled monolayer (SAM) on polycrystalline gold electrode surface, which can exist for several days without changing its electrochemical properties. The SAMs of 8-mercaptoquinoline selectively catalyzed the reduction of Ga 3+, In 3+ and Cr 6+ while blocked the electrochemical reaction of other metal ions on the electrode surface. It was also found out that the SAMs of 8-mercaptoquinoline selectively catalyzed the oxidation of NADH, uric acid and ascorbic acid. © 2003 Published by Elsevier B.V.
