Nanoelectrode and its array in electrochemical applications can provide greater advantages such as fast response times, enhanced mass transport and sensitivities compared with its corresponding planar or micro-electrodes. Therefore, the fabrication of nanoelectrode arrays has attracted increasing attention, and has been developed by applying various techniques. In this work, the gold nanoelectrodes coated with vertically-oriented cylindrical nanopores are fabricated for the sake of electrochemical dopamine sensing. The structure of periodic nanoporous membranes was generated by the self-assembly of block copolymers (BCPs). The effects of thickness of films, scan rate, concentration of diffusion species, and pH of electrolytes were indicated by the array of gold nanoelectrodes. The morphologies of membranes were characterized by AFM and SEM, and the electrochemical analysis of nanoelectrodes from nanoporous membranes was optimized by CV measurements. |
