Abstract
A sensor for detecting microorganisms in air, water, or deposited on surfaces. The sensor includes a source of light, a waveguide receptive to the source of light, a fluorochrome coating on the waveguide, and a detector which detects the Stokes shift of light passing through the waveguide in response to microorganisms fluorescing as they come into contact with the fluorochrome coating on the waveguide.
