Claim:
1. A biological material detector, comprising: an air chamber comprising a physical structure creating an enclosure; an emitter assembly operatively coupled to said air chamber, wherein said emitter assembly includes an emission source producing a wavelength of light to excite fluorescence in biological material; an optical detector, wherein said optical detector further comprises a prism operatively connected to said optical detector; means for capturing a sample of biological aerosol material from air in said air chamber, said means for capturing biological material positioned between said emitter assembly and said optical detector and contained within said air chamber, and wherein said means for capturing comprises a capture assembly which comprises: a substrate operatively connected to said air chamber; a ligand operatively connected to said substrate; and a capture material operatively connected to said ligand; and an optical filter positioned between said optical detector and said capture assembly, wherein said filter attenuates light wavelengths other than fluorescence light wavelengths produced by the fluorescing biological aerosol material; and wherein said optical detector is operatively connected to said capture assembly and said optical filter, and said detector is capable of detecting fluorescence generated directly by biological aerosol material captured on said capture assembly; and a protective housing enclosing said biological detector, an air passage bored through said protective housing.
