Abstract :
In this work we report on the fabrication and characterization of single-walled carbon nanotubes (SWCNTs) as sensitive layers for the detection of simulants of Chemical Warfare Agents (CWAs). The microsensor fabrication has been achieved after the wafer scale integration of the selective synthesis of SWCNTs as sensitive layer. Their electrical characterization has been carried out by measuring the resistance changes of the SWCNT networks when interacting with very low concentrations of CWA simulants such as dimethyl methyl phosphonate (DMMP), dipropylene glycol methyl ether (DPGME) and dimethylacetamide (DMA) at low temperatures, which are simulants of Sarin, Nitrogen Mustard and Distilled Mustard, respectively.
