Abstract
A sensor-network system for spectrally sensing a chemical or biological substance includes a plurality of probe assemblies that each includes a sensor comprising a nano structured surface, wherein the nano structured surface can adsorb molecules of a sample material captured adjacent to the sensor; a laser configured to emit a laser beam to illuminate the molecules adsorbed to the nano structured surface, and a spectrometer that can obtain spectral data from light scattered by the molecules adsorbed to the nano structured surface. A control center includes a computer storage configured to store spectral signatures each associated with a chemical or biological substance and a spectral analyzer that can determine a spectral signature matching at least one of the spectral signatures stored in the computer storage thereby to identify, in the sample material, the chemical or biological substance associated with the one of the spectral signatures.
