ABSTRACT:
Methods of monitoring analyte concentration in fluids using fiber optic sensors that include analyte permeable matrices disposed in a light path at one end of an optical fiber waveguide. The analyte permeable matrix includes an indicator molecular capable of responding to the analyte in an optically detectable manner. The absorbance or emission from the analyte permeable matrix after irradiation is used to determine the concentration of the analyte in the fluid as a function of the measured absorbance or emission. Methods for manufacturing fiber optic sensors useful in a method of monitoring analyte concentration in a fluid include casting a polymer film that includes an indicator molecule capable of responding to the analyte in an optically detectable manner. Disks or pellets are punched from the film and applied to the end of an optical fiber waveguide.
