title: The development and application of FET-based biosensors.
abstract: After having considered the general definition of biosensors, the specifications of one type are discussed here in more detail, namely the pH-sensitive ISFET, which is at present being clinically investigated for intravascular blood pH recording. Results, advantages and possible improvements will be discussed, as well as a prediction with respect to future developments of FET-based biosensors.
