  • Filter systems including optical analyte sensors and optical readers
    Patent number: 8821621
    Abstract: A filter system includes a housing, a filter medium disposed within the housing and a optical analyte sensor also disposed within the housing in fluid communication with the filter medium. The optical analyte sensor includes a detection medium that changes at least one of its optical characteristics in response to an analyte. The filter system further includes an optical reader having at least one light source and at least one detector. The optical reader is attached to the housing such that at least a portion of light emitted by at least one light source is reflected from the optical analyte sensor and captured by at least one detector.

  • Filter Systems Including Patterned Optical Analyte Sensors and Optical Readers
    Publication number: 20130186279
    Abstract: A filter system includes a housing, a filter medium disposed within the housing, an optical analyte sensor, and an optical reader. The optical analyte sensor is characterized by a first region that exhibit a first response to an analyte of interest and a second region that exhibit a second, different, response to an analyte of interest. The optical analyte sensor includes a detection medium and is disposed within the housing such that the detection medium is in fluid communication with the filter medium. The optical reader includes at least one light source and at least one detector.
