The possibilities of interfacing neurons with nano-fabricated structures bring about very exciting opportunities to develop biosystems with a wide variety of applications. Even though the electrical impulses of a neuron has been studied for decades using micro-fabricated devices, a fundamental issue in the development of such systems remains outstanding, i.e. the ability to reliability pattern neurons at specific locations and in specific topologies such that they remain viable and make connections with neighboring neurons. If the cells can be selectively placed where needed, then site specific electrical signals can be detected from individual cells and high sensitivity detectors can be realized since a very small amount of toxins will be needed to affect a single cells. We envision a micro/nano-fabricated system where neurons have been defined and placed in closed 3-D channels and wells, electrodes and transistors are fabricated and integrated within the channels, and nutrients are supplied to the cells to keep them alive. The neurons will be patterned using electrical field induced directional growth of the processes. The electrical activity of these cells would be examined along with their metabolic activity and the changes in the electrical activity would be studied under the exposure to toxic chemicals and bio-warfare agents.
