Enzyme biosensor for urea based on a novel pH bulk optode membrane

A new, absorbance-based enzymatic biosensor membrane for determination of urea is described. A lipophilic, fully LED-and diode laser-compatible pH sensitive dye was incorporated into a plasticized, carboxylated poly(vinyl chloride) membrane and served as the optical transducer of the sensor. Urease...
