  • Hand-held fluorescence polarimeter
    Patent number: 7528952
    Abstract: A small, portable, hand-sized apparatus for detecting microorganisms or chemicals in liquid samples by fluorescence polarization. The apparatus operates using a low power excitation light source, such as an LED, in order to irradiate a sample with polarized light. Detection of emitted polarized light from the sample is detected in multiple planes simultaneously using low power detectors resulting in an elimination of error caused by drifts in intensity in sequential measurements and in reducing assay time.
    Type: Grant
    Filed: June 2, 2005
    Date of Patent: May 5, 2009
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Malford E. Cullum, Istvan Naday, Alan L. McArthur
