Abstract
The present invention provides a unique fiber optic sensor which is able to provide a viewing zone for visual examination of a sample and its surrounding environment; and is able to conduct multiple assays concurrently using a plurality of different dyes immobilized at individual spatial positions within a dye sensing zone on the surface of the sensor. The present invention also provides apparatus for making precise optical determinations and measurements for multiple analytes of interest concurrently and provides methods of detection for multiple analytes of interest which can be correlated with specific parameters or other ligands for specific applications and purposes.
