Abstract:
A method of detecting trace amounts of nitro-containing organic species or chemical warfare agents within an environment comprising:placing a selected chemical sensor into an environment, said sensor including a substrate having an oxide surface layer thereon and a selective thin film of a cyclodextrin derivative chemically bound upon the substrate, said film adapted for the chemically bonding of a nitro-containing organic species or a chemical warfare agent therewith, for a sufficient time wherein nitro-containing organic species or chemical warfare agents can form complexes with said cyclodextrin derivative;measuring a change resulting from complexation of nitro-containing organic species or chemical warfare agents with said cyclodextrin derivative;correlating said measured change with a quantitative or qualitative output relating to said nitro-containing organic species or chemical warfare agents.
