Abstract
Provided are compositions and systems useful in remote monitoring of chemical hazards, air quality, and medical conditions, for example, robotic systems to search for and detect explosives, mines, and hazardous chemicals. In addition, the methods, systems and compositions of the invention provide the ability to mine data from a database containing a plurality of chemical fingerprints.
Claims21
A method for characterization of a gaseous or vapor sample, comprising:
- contacting at least one sensor with a gaseous or vapor sample, wherein the sample contains at least one analyte, the at least one sensor comprising a composite having regions of an electrically conductive material and a material compositionally different than the electrically conductive material and wherein the at least one sensor provides a detectable signal when contacted by the at least one analyte;
- converting the detectable signal to a digital representation of the detectable signal;
- comparing the digital representation to a database of digital representations of known analytes;
- identifying a match between the digital representations;
- transmitting data corresponding to the match and data associated with the matched digital representation to a remote location via the internet, fiber-optic cable, and/or an air-wave frequency;
- and
- storing the data on a storage device.
