Immunochemical Detection of an Explosive Substance in the Gas Phase through Surface Plasmon Resonance Spectroscopy


Description of Technology:

This technology is a biosensor element to be used in combination with Surface Plasmon Resonance Spectroscopy (SPRS) for immunochemical detection of an explosive substance. The biosensor comprises a specially designed surface which can be optically coupled to a Surface Plasmon Resonance (SPR) spectrometer. The biosensor surface can be comprised of a substrate of the same material as the SPR optical component and can be metalized. A chemical layer consisting of a thiol can be reacted onto the surface as a Self Assembled Monolayer (SAM). Onto this reactive SAM, biomolecules such as antibodies, antibody fragments, proteins or other substances can be reacted with the SAM producing a biosensor surface which can be utilized in the detection process.


This technology can be used for the detection of drugs in blood, fluid or breath, as well as detecting airborne biological weapons. Police forces, military forces, security personnel and healthcare providers can utilize this technology.

Features and Benefits:

Benefits include use as a portable device, the low cost of such a device, improved safety and rapid detection of certain compounds present in air or liquids.
