| Abstract
| - Taking advantage of both the self-organizing characteristics and the amphiphilic property of poly(styrene-block-ethyleneoxide) (P(S-b-EO)), we have realized one-step fabrication of nanoelectrode ensembles(NEEs). By choosing the electrolyte solution elaborately, only the poly(ethylene oxide) (PEO) segment inthe P(S-b-EO) film was swollen to serve as nanoscale tunnels for solvated ions, whereas the polystyrenesegment remained robust to be the electrode mask. An electrochemical analysis indicated that a transitionbetween linear diffusion and nonlinear diffusion could be observed due to the small diffusion coefficientof ferrocene in PEO nanodomains.
