| 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/SAM structure has a higher stability, and E 1/2 of the DBAH in MD/SAM shifts 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. |
