ABSTRACT:
The optical fiber microsensor includes an optical fiber having a portion of the surface of a light conducting core covered with a layer containing an analyte sensitive dye material. The dye indicator material is covalently bonded to a copolymer which is covalently bonded to a blocked polyether polyisocyanate. The resulting polymer is covalently bonded to the optical fiber core to prevent leaching of the indicator dye material during extended use.
