Optical fiber pH microsensor and method of manufacture |
摘要 |
The optical fiber pH microsensor includes an optical fiber having a portion of the surface of a light conducting core covered with a layer of a pH sensitive dye material. The dye material is covalently bonded to a polymeric matrix which is in turn covalently bonded to the optical fiber core to prevent leaching of the indicator dye material during extended use. The dye material is crosslinked in situ over the tip of the optical fiber to yield a hydrophilic, ion permeable pH sensor which can be used intravascularly to monitor blood
