dc.description.abstract | Herein, we present a novel electrochemical sensing platform that consists of a set of suspended carbon nanowire-based mesh electrode with deliberately controlled shapes (hexagonal or diamond), and a substrate-bound planar carbon electrode. These electrodes overlapped one another with a pre-defined gap which was precisely controlled by using a polymerization-stop layer. By recycling the redox reactions between the electrodes with a 2.1-μm-gap, the redox current of Fe(CN)6 4-/Fe(CN)6 3- could be amplified approximately 37 times. This high current amplifying capability enabled dopamine detection down to 5 μM using cycling voltammetry. The complex morphology of the stacked carbon structures was obtained by simply using multiple UV-lithography processes and a single pyrolysis process that allowed pre-defined polymer structures to shrink into sub-micrometer-scale carbon structures. The suspended carbon mesh structures confined the mass-transfer near the electrode overlap region, and hence, the electrode set operated as a "sandwich" electrode enclosed within a microchannel. This effect was studied by simulating the mass transfer of the redox species, and confirmed by electrochemical measurements. | - |
