toc_LC2We suspended a single nanoskived gold nanowire in a microfluidic channel. In this preliminary report, a 200-nm-diameter nanowire was used as an electrode to perform hydrodynamic voltammetry in the center of solution flow. Suspended nanowires exhibit superior current response due to highly efficient mass transport in the area of fastest flow.
