摘要：
Silicon nanowires (SiNWs) with the length of several hundreds of micrometers and an average diameter of 15 nm were successfully synthesized via a thermal-evaporation oxide-assisted process. Then, a convenient method was applied to metallize the SiNWs just by dipping them into an aqueous deposition solution. During the metallization process, which is a redox reaction, gold nanoparticles (NPs) were prepared on SiNWs surface to confine the particle size and prevent agglomeration during the preparation and utilization of gold NPs. The synthesized SiNWs decorated with gold NPs were utilized to modify the glassy carbon electrode. Electrochemical measurements displayed that the modified electrode showed high sensitivity for dopamine (DA) detection.
