摘要: Nanoscaled electrode has been attracting increasing attention because of striking fundamentals and practical applications. Usually, the nanoscaled is fabricated by manual or photo electron-beam lithography, which not easy to reproducibly fabricate with simple equipment. In this paper, a cost-effective method, nanoskiving, developed an ultralong nanowire (ULNE). The ULNE obtained simply sectioning sandwich epoxy block Au film. width could be down nanometer dependence on thickness film, while length reach millimeter. Thus, created shows steady-state microamperometric current, characteristic nanoelectrode array attributed its macroscopic without considering overlap diffusion layer neighboring nanoelectrode. electrodeposited Pt/Au displays unusual electrocatalytic performance toward both oxidation reduction hydrogen peroxide and, as nanosensor, gives rise high sensitivity selectivity monitoring released from cells stimulated ascorbic acid.
