Figure 2From: pH-triggered conduction of amine-functionalized single ZnO wire integrated on a customized nanogap electronic platformThe 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.Back to article page
