title: Development of an optical fibre sensor for ammonia, urea, urease and IgG.
abstract: An optical fibre sensor utilizing Brilliant Yellow in a thin cellulose acetate membrane as a pH sensor has been developed. By use of gas permeable membrane, urease-immobilized membrane and IgG immobilized membrane we obtained optical sensors for ammonia, urea, urease, IgG suitable for physiological and clinical applications. The system makes use of commercially available instrumentation for absorbance measurement and flow cell for fast analysis.
