The nanogap array platform and the FESEM image of the ZnO microwires. (a) The gold electrode array chip, having eight nanogaps, mounted on the PCB (left) and the customized nanocube electronic board (right). (b) FESEM image of the ZnO microwires with X-ray diffraction pattern. (c) Amine-functionalized ZnO-NH2 wires dielectrophoretically aligned across the nanogap, bridging the two gold electrodes.
