Monitoring network based on nano-structured sensing devices

A monitoring network system for inspecting and controlling harmful substances, comprising:

• a plurality of probe assemblies each comprising:
• a sensor configured to adsorb or bind with 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 obtain 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;
• a plurality of central offices that are connected in a computer network, wherein each of the central offices comprises:
• 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 one or more of the plurality of probe assemblies;
• and
• 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 plurality of central offices, 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 in one or more of the plurality of central offices.
