Abstract: The self assembled monolayer of cystamine was prepared on gold electrode and 3,4-dihydroxybenzoic acid(DHBA) was electrochemically deposited on cystamine surface as a functional group by electrostatic adsorption, namely, molecular deposition. It shows that the MD/SAMstructure has a higher stability, and E1/2 of the DBAHin MD/SAMshifts more negative than that of on naked gold electrode. The n-decanethiol was also used to fill defects in MD/SAM, it results in much better cyclic voltermmetric behavior.

Key words: Chemically modified electrode, Self-assembled monolayer, Molecular deposition, 3,4 Dihydroxybenzoic acid
