| 摘要 |
A non-mediated enzyme electrode comprises a base substrate ( 2 ) on which is provided an electrically conductive base layer ( 8 ) comprising finely divided platinum group metal or oxide bonded together by a resin; a top layer on the base layer ( 8 ), the top layer comprising a buffer. A catalytically active quantity of an oxidoreductase enzyme is provided in at least one of the base layer and the top layer. The invention also provides a biosensor ( 20 ) which includes an enzyme electrode, and methods of manufacturing the enzyme electrode and biosensor.
