Abstract: A method and system for detecting the presence of chemical and/or biological agents are disclosed. An additive, which may comprise a reactant and/or a catalyst selected for its capacity to react with, or to force a reaction involving a target chemical and/or biological agent, may be introduced into a sample of an ambient environment to be monitored. The additive may then react with the target agent, or, as a catalyst, may drive a reaction with the target agent, resulting in a reaction product that may be detected by one or more sensors or sensor arrays. The method and system may incorporate a plurality of sensor types in order to enhance the specificity of the method and system.
