Cyclic voltammogram of a suspended carbon nanowire (a) and simulated 2-D concentration profiles (b,c). (a) A cyclic voltammogram was collected from a suspended carbon nanowire (diameter approximately 190 nm) in 10 mM K3Fe(CN)6 and 0.5 M KCl solution; the monolithic carbon structure was insulated with a negative photoresist pattern except for the 43-μm-long middle section of the nanowire. 2-D concentration profiles were simulated for (b) a suspended nanowire and (c) a surface-bound nanowire structure with the same section areas as the carbon nanowire used in the cyclic voltammetry as in (a).
