  • Methods and apparatus to improve the sensitivity and reproducibility of bioluminescent analytical methods
    Patent number: 6927851
    Abstract: A hand-held assay device measuring chemiluminescence generated by as ample of ATP or other entity capable of chemically reacting to generate photoluminescence includes a photodiode detecting light which is emitted from the sample to produce a sample signal, another photodiode generating a reference signal in response to environmental changes, switched integrators amplifying the sensor signal over a controllable integration time to detect an output signal indicative of the presence of the sample.
    Type: Grant
    Filed: March 29, 2001
    Date of Patent: August 9, 2005
    Assignee: Neogen Corporation
    Inventors: John T. McCaffrey, Szilveszter Jando, Sunita Carrasko
