Abstract
A point of use analyte detection and quantification system for food or food processing applications is provided. Related methods are also provided.
Claims22
A portable interferometric system for detection and quantification of analyte within a food processing test sample composition, the system comprising:
- an optical assembly unit, the optical assembly unit comprising a light unit and a detector unit each adapted to fit within a portable housing unit;
- and
- a cartridge system adapted to be inserted in the housing and removed after one or more uses, the cartridge system comprising:
- an interferometric chip including one or more waveguide channels having a sensing layer thereon, the sensing layer adapted to selectively bind or otherwise be selectively disturbed by one or more analytes within the food processing test sample composition;
- a flow cell wafer;
- and
- a cartridge housing enclosing the interferometric chip and flow cell wafer.
4 more elements
A method of detecting and quantifying the level of analyte in a food processing test sample composition, the method comprising the steps of:
- collecting a food processing target sample containing one or more analytes;
- introducing the chemical target sample to a portable interferometric system;
- initiating waveguide interferometry on the test sample composition;
- and
- processing any data resulting from the waveguide interferometry,
- wherein the portable interferometric system comprises:
- an optical assembly unit, the optical assembly unit comprising a light unit and a detector unit each adapted to fit within a portable housing unit;
- and
- a cartridge system adapted to be inserted in the housing and removed after one or more uses, the cartridge system comprising:
- an interferometric chip including one or more waveguide channels having a sensing layer thereon, the sensing layer adapted to selectively bind or otherwise be selectively disturbed by one or more analytes within the food processing test sample composition;
- a flow cell wafer;
- and
- a cartridge housing enclosing the interferometric chip and flow cell wafer.
