Air

 Detection of potential biothreat agents in air remains a pressing concern for both the Defense Department and Homeland Security. The desired product is one that continuously filters and concentrates large volumes of ambient air into a small volume of liquid sample that can be rapidly analyzed on a biosensor linked to the concentration system. Such an autonomous monitoring system could be placed within critical infrastructure such as subways, airports and buildings or in selected outdoor areas such as football stadiums. Using the SASS 2000 air collection system (Research International) to generate test samples, ABL researchers have been developing methods to rapidly assay air concentrates for pathogens of interest.

Powders

In addition to aerosolized biothreat agents in air samples, detection of agents in powders is also a high priority. Recent use of powders to spread Anthrax through the U.S. Postal Service in 2001 demonstrates the need for rapid detection of suspect powders. ABL researchers have developed methods for detection of Bacillus anthracis spores in powders such as talc, sugar, cornstarch, and baking soda (see Tims and Lim, 2004).
