US Patent 7176793 - Nanodetectors for cargo container security

There is interest in improving cargo container security since cargo containers can be used as a vessle for potentially harmful material (explosives, chemical weapons, etc.) This patent suggests the use of "nanodetectors" to assist in identifying such threats. Unfortunately the one page specification does not give much detail on the types of "nanodetectors" utilized. Claim 1 reads:

1. A detection strip for an enclosed container, comprising: a) many nano detectors for detecting materials, harmful to human beings, within an enclosed container and transmitting a corresponding resonance frequency, b) a serial number computer chip for identifying the detection strip and transmitting a corresponding resonance frequency, and c) a power source for operating the detection strip.
