Electrode, provided with a polymer coating with a redox enzyme bound thereto

Abstract

Abstract The invention relates to an electrode which is composed of a membrane, provided with open pores running through said membrane, the walls of the pores having an electrically conducting polymer coating, containing a redox enzyme bound thereto. In this type of electrodes a direct electron transfer is possible between the redox enzyme e.g. glucose oxidase and the electrically conducting polymer e.g. polypyrrole. Such an electrode, which can be produced in a simple manner, has extensive application possibilities such as, for example, in a biosensor or in a production installation for the preparation of specific chemicals. As starting materials for the electrodes of the invention use can be made of marketed porous membrane materials as well as of latex particles. The walls of the pores of the porous membrane and the interstices of the latex particles respectively are provided with a thin layer of the electrically conducting polymer which on its turn is provided with a redox enzyme suitable for the pursued aim.
