摘要：
We are investigating the utility of UV light emitting diodes (LEDs) as the excitation source for fluorescence-based biological agent detection. These LEDs may enable the development of small and low-cost biological agent detectors. We have designed, and are currently fabricating, a test bed using UV LEDs for detecting biological agent aerosols. Using an experimental apparatus, we have measured the elastic scattering and fluorescence signals from single bacterial spores illuminated by low-power 408-nm laser diode radiation.
