Abstract
The invention is directed to a swipe with at least one ionization reagent associated with the swipe for detecting target analytes and methods of detecting the target analyte molecules that can indicate the presence of, for example, explosives, narcotics, chemical warfare agents, biological warfare agents, or toxins. The swipe can be used to transfer molecules from a surface to the swipe for further analysis. In particular, the swipes can include an ionization reagent that is preferably a low volatility compound and capable of forming ionization reagent-analyte complexes with target analytes. The swipe can also include multiple ionization reagents with different volatilities such that they are released sequentially during a thermal ramp-up. Alternatively, the swipe can have multiple ionization reagents associated with spatially separated portions of the swipe such that they can be releasable sequentially to detect multiple target analytes.
