Abstract
An improved fiber optic sensor, sensing apparatus, and methods for making optical determinations are provided. The fiber optic sensor employs a fiber optic strand to convey light energy and at least one polymer matrix comprising a fluid erodible, continuous release polymer and a releasable reagent formulation able to react with a molecule or analyte of interest. The optic sensors and sensor construction has been demonstrated to be accurate, precise, and of long duration.
