A new type of enzymatic sensors for the determination of urea based on an ionophore-free pH membrane electrode has been constructed. The membrane material was polyvinyl chloride modified with 1,4-diaminobutane. Chemical urease immobilization enabled the formation of a mono-and bimolecular enzyme la
For the design of a biosensor sensitive to steroidal glycoalkaloids, pH-Sensitive Field Effect Transistors as transducers and immobilised butyrylcholinesterase as a biorecognition element have been used. The total potato glycoalcaloids can be measured by this biosensor in the concentration range 0.5
