ABSTRACT:
The illustrative embodiment of the present invention is a system and a method for the detection and identification of biological agents. The system incorporates elements that enable it to obtain an air sample, extract particulates from the air sample onto a stationary-phase collection media, expose the particulates to electromagnetic radiation, and monitor for fluorescent emissions. In some embodiments, particulates are exposed to electromagnetic radiation using a plurality of LEDs, wherein some of the LEDs emit electromagnetic radiation at relatively shorter wavelengths and some other of the LEDs emit electromagnetic radiation at relatively longer wavelengths.
