Tech Brief: Our technology enables direct electrochemical deposition of nanowires on sensor chips from solution. It is a simpler and less capital-intensive room temperature process, compared with current nanofabrication processes. The sensing parameters are tunable by a wide range of materials selection. It is compatible with flexible electronics.

Value Proposition: Our nanowire sensor technology enables domestic manufacturing of advanced nanowire sensors for antiterrorism applications. Our innovation addresses an unmet need in scalable nanomanufacturing of nanowire sensors, which requires precise placement of nanowires as the ultrasensitive sensing unit onto electronic substrates. The lack of nanomanufacturing solutions has prevented rapid growth of domestic nanosensor market despite tremendous progress in nanomaterials research and nanotechnology. Our innovation is a solution crystallization process that synthesizes and places nanowires directly and precisely on microelectronic substrates. It further improves materials selection for sensing and reduces the cost of nanosensor manufacturing. We expect that the ultimate cost of our nanosensor to be significantly less than commercial nanosensors after successful prototyping and commercial application validation. Compared with the existing nanowire sensor fabrication methods, our technology has 4 main advantages. 1) By direct deposit of a solution droplet, nanowires are created right on chips or micro-fabricated devices. 2) It is a room temperature fabrication process, thus enabling less complex and capital-intensive manufacturing process. 3) It is a modular method that enables combinatory synthesis of a wide range of new organic nanowires. 4) It is a fabrication technology compatible with flexible electronics platforms. We expect the commercial-ready version of the technology to be available in 3 years after prototyping and application validation.
