A HYDROGEL, FOR USE IN A BIOSENSOR WITH OPTICS BASED DETECTION OF ANALYTES

摘要

The present invention discloses a hydrogel comprising a mixture of a capture agent and a detection agent, wherein the mixture is randomly distributed within the hydrogel. There is also provided a detection device for measuring analyte levels in a sample fluid comprising the hydrogel and an optical waveguide substrate. Also disclosed is a method of measuring analyte levels in a sample fluid comprising contacting the sample fluid with the hydrogel of the detection device; transmitting light through the optical waveguide substrate; and detecting a signal through the optical waveguide substrate, wherein strength of the signal detected indicates the amount of analyte in the sample fluid.
