Electrical Nerve Agents Sensors Based on Chemically Functionalized Nanomaterials

The threat of a chemical attack continues to grow and recent examples such as the terrorist attack of the Metro of Tokyo have shown that organophosphorus agents (OPs) are powerful neurotoxic weapons. There is still [...]

Innovative Gas Sensors for Sub-ppm Detection of Organophosphorus Nerve Agents by Chemically Functionalized Carbon Nanotube Field-Effect Transistors

Carella A., Caillier L., Clavaguera S., Celle C., Simonato J-P, CEA, FR

In this communication, we will present innovative sensors based on carbon nanotube field-effect transistors (CNT-FET) for detection of organophosphorus agents (OP, Sarin-like molecules). We have functionalized CNT with organic moieties reactive towards OPs that form [...]

Nanopore detection of nerve agent degradation products

Guan X., Gupta J., Zhao Q., de Zoysa R.S., Jayawardhana D.A., The University of Texas at Arlington, US

Improved analytical capability for detection of organophosphate chemical agents (i.e. nerve gases) remains a high priority need in our continuing defense against future terrorist attacks. A nanopore stochastic sensing method for the rapid detection of [...]
