Zusammenfassung: | A novel approach for the construction of a micro biosensor on the base of amperometric enzyme microelectrode arrays is described in this paper. The technique contains the electrochemical deposition of different enzymes in a conducting organic polymer,
e.g. polypyrrole, on a transducer built up with the help of microfabrication technology. The electrochemical characteristics of these microelectrode arrays can be compared to conventional microelectrodes with the advantage of higher current outputs. For the first time different model enzymes like glucose oxidase, choline oxidase and lactate oxidase have been tested showing the principal possibility to construct a micro biosensor on the base of ultramicroelectrode arrays. |
