Abstract
A fibre-optical sensor has been developed based on the fluoresecent in dicator 8-hydroxyl-1,3,6-pyrene trisulphonic acid trisodium salt (HOPS A) for monitoring physiological pH values. Dowex-1 strongly basic anio n exchange resin is used as the medium to immobilise the indicator on the end of an optical fibre. Polyurethane is coated on the sensor as t he permeable membrane for H+. The properties of HOPSA in solution, as well as when immobilised on the sensor, are studied and found to have the potential for monitoring physiological pH values.
