  • Patent number: 4900423
    Abstract: An enzyme sensor comprising an enzyme acting specifically on a substrate and a transducer for converting the quantitative change of a substance or heat which is produced or consumed during an enzyme reaction to an electrical signal, wherein the enzyme is glucokinase is disclosed. By the enzyme sensor of the present invention, an accurate determination of an amount of glucose in a sample is possible as well as an accurate determination of adenosine-5'-triphosphate (ATP). A response time of the sensor is almost constant after a long-term use and a decrease of the detecting ratio is very small.
    Type: Grant

    Date of Patent: February 13, 1990
    Assignee: Unitika Ltd.
    Inventors: Takeaki Iida, Takeshi Kawabe
  • Patent number: 4812220
    Abstract: Disclosed is an enzyme sensor for determining a concentration of glutamate comprising an immobilize enzyme acting specifically to a substrate and a transducer for converting the quantitative change of a substance or heat which is produced or consumed during an enzyme reaction to an electrical signal, wherein the enzyme is glutamine synthetase and the transducer is the pH glass electrode or ion-sensitive field-effect transistor (ISFET). The enzyme sensor can be miniaturized and can accurately determine a concentration of glutamate even when it is low.
