Paper Abstract

Bio-aerosol terrorist attacks have been carried out against civilians in the United States and elsewhere. Unfortunately, recurrence appears inevitable. A fast, reliable, and inexpensive bioaerosol threat detection trigger can be an important tool for detect-to-protect and detect-to-treat countermeasure scenarios. Bio-aerosol threat detection triggers employing light, historically laser light but recently LED light, for induced native- or auto-fluorescence (LIF) have been developed for well over a decade without a generally accepted solution being found. This paper presents a brief history of LIF triggers and reviews many vendor efforts, past and current. Various technical approaches and design considerations are discussed. Triggers from ICx technology, currently available or in development, are also discussed.
