United States Patent 5,272,087 (Dec. 21, 1993)

Enzymatic electrode and its preperation method

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.

Electrode enzymatique et son procédé de préparation.

Cette électrode consiste en une matrice 7 réalisée à partir d'une poudre conductrice et renfermant au moins une enzyme immobilisée de façon homogène dans sa masse. Elle présente une surface utile 9 renouvelable par frottement ou découpe, de telle sorte que sa surface soit toujours identique à elle-même. Elle peut cependant être du type à usage unique, jetable. Cette électrode peut être utilisée dans tous les domaines mettant en jeu des réactions enzymatiques, en tirant profit de leur sélectivité, par example, pout les dosages dans l'industrie chimique, dans les domaines médicaux et biologiques, ainsi que dans les industries agro-alimentaires.
