  • Method and apparatus for sensing the presence of microbes
    Patent number: 5968766
    Abstract: Method and apparatus for the detection of aerobic microbes on non-living surfaces in which electromagnetic radiation having a wavelength greater than 350 nm is directed onto the surface to cause excitation of pyridine nucleotides present in microbial cells to emit radiation having a higher wavelength. That higher wavelength radiation and reflected radiation is then sensed as a measure of the amount of microbial cells on the surface.
