A silver wire electrode coated with a poly (vinyl chloride)/tri-n-dodecylamine composite membrane was used to fabricate potentiometric enzyme sensors. The coated Ag electrode was further covered with a penicillinase or urease membrane to make a penicillin or urea sensor, respectively. The penicillin sensor was useful for determining penicillin at concentrations of millimolar level. Some operating variables such as pH and ionic concentration of the working buffer of the sensor were examined. The urea sensor could be used to determine urea in human blood.
