| Abstract: | A cysteamine (CysAm) nanostructure was generated to act as an intermediate layer between gold electrode and carbon nanotubes. A bare gold electrode was placed in a solution of CysAm to create a self-assembled monolayer on its surface. The modified electrode was then incubated with a solution of multi-walled carbon nanotubes. Cyclic voltammetry and atomic force microscopy were used to characterize the modified electrode. The results indicated that the number of functionalized MWCNTs on the surface of the electrodes increased by enhancing incubation time. The aim of this paper is to investigate the variations of incubation time of bare gold electrode inside cysteamine solution for immobilization of MWCNTs on cysteamine modified electrode. It is found that the number of functionalized MWCNTs on the surface of cysteamine modified electrode increased by enhancing incubation time bare gold electrode inside cysteamine solution. |
