PCT No. PCT/FR89/00182 Sec. 371 Date Oct. 16, 1990 Sec. 102(e) Date Oct. 16, 1990 PCT Filed Apr. 19, 1989 PCT Pub. No. WO89/10395 PCT Pub. Date Nov. 2, 1989.An enzymatic electrode, having a homogeneous composition throughout, consists essentially of a uniform intimate admixture of a conducting powder with at least one immobilized enzyme, or with an immobilized enzyme and a mediator agent or a co-enzyme, in a matrix. The electrode is one which has a surface available for direct contact with a substrate without a permeable or semi-permeable intermediate membrane or membranes. The enzymatic electrode is prepared, e.g., by intimately admixing (a) a homogeneous paste or matrix (resulting from an intimate admixture of a conducting powder with a binder), (b) at least one enzyme and (c) an enzyme crosslinking solution, and then incorporating therein a mediator agent and/or a co-enzyme.
