Abstract
Exposure of nanoparticles of Ag to 2-CEES (2-chloroethyl ethylsulfide, a simulant of the sulfur mustard warfare agent) was found to cause a significant change in the film conduction characteristics that could be used as a sensitive method of detection. Ag nanoparticles deposited onto highly-ordered pyrolitic graphite, glass, and polyethylene substrates were found to form such films. Uptake of 2-CEES was irreversible and cumulative. The sensitivity and cumulative nature make the nanoparticle films most appealing as personal exposure indicators.
