Patent ID: 8582099

Claim:
A monitoring network system for inspecting and controlling harmful substances, comprising: a plurality of probe assemblies each comprising: a sensor comprising nano structured surfaces, configured to 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 surfaces; a spectrometer configured to produce spectral data from light scattered by the molecules adsorbed to the nano structured surfaces; and a ID reader configured to retrieve identification information about the sample material; and a central office in communication with the plurality of probe assemblies, comprising: a computer storage configured to store one or more spectral signatures each associated with a harmful substance and the identification information for the sample material; a communication device configured to receive the spectral data and the identification information from the plurality of probe assemblies; a spectral analyzer configured to determine, in the spectral data, a spectral signature matching at least one of the spectral signatures stored in the computer storage thereby to identify, in the sample material, the harmful substance associated with the one of the spectral signatures; and an alert and response system in communication with the spectral analyzer, wherein the alert and response system is configured to send out an alert signal about the sample material when the harmful substance is identified in the sample material.
