1. An apparatus for detecting light-emitting material in a sample comprising:

  • a light-emitting component;

    a light-detecting component;

    a lock-in amplifier;

    a frequency generator operatively coupled to the lock-in amplifier and the light-emitting component;

    a sound transducer that is capable of emitting a humanly detectable signal wherein the signal varies with magnitude of detected fluorescence in the sample; and

    a visible output of relative fluorescent intensity where the visible output varies with the magnitude of the detected fluorescence in the sample.
