Abstract
The present invention provides fiber optic sensors, apparatus, methods of optical detection, and methods of sensor manufacture for detection of organic analytes having a fixed polarity. The sensor requires an optical fiber strand; an immobilized polarity-sensitive dye; and an immobilized polymeric material which not only contains the polarity-sensitive dye but also absorbs and partitions the organic analyte of interest.
