use of the production of diffraction based on where the winning project

摘要

The present invention provides an inexpensive and sensitive device and method for detecting and quantifying analytes present in a medium. The device comprises a metalized film upon which is ink-jet printed a specific, predetermined pattern of binder, such as an antibody. Upon attachment of a target analyte to select areas of the plastic film upon which the binder is printed, diffraction of transmitted and/or reflected light occurs via the physical dimensions and defined, precise placement of the analyte. A diffraction image is produced which can be easily seen with the eye or, optionally, with a sensing device.
