Abstract

Nanomaterials come in a wide range, and each one has distinct electrical, optical, and sensing capabilities.However, there is currently no paradigm for the low-cost, high-throughput integration of several nanomaterials on a single chip. To produce a scalable array of individually addressable assemblies of graphene, carbon nanotubes, metal oxide nanowires, and conductive polymers on a single chip, we describe a high throughput integration technique based on successive spatially controlled dielectrophoresis [1]. This is the first time that a single chip has had such a variety of nanomaterials built on the same layer. The size and spacing of the underlying electrodes on the chip utilised for assembly are the only factors that restrict the resolution of assembly, which can range from mesoscale to microscale.The utility of such an array is illustrated with an example application of a chemical sensor array for detection of volatile organic molecules below parts-per-million sensitivity, despite the fact that many applications are feasible [2].
