<p>The electrode is characterized in that its enzymatic part and its detection part are combined, said electrode being comprised of a matrix (7) made from a conducting powder providing for the detection and containing, intimately mixed with said powder, at least one immobilized enzyme incorporated homogeneously into its mass, said electrode being directly in contact with the substrate to be dosed without permeable or semi-permeable intermediary membrane or membranes. The electrode has a useful surface (9) which is renewable by friction or cutting so that its surface remains always equal. However, it may be of the disposable type, with one use only. Said electrode may be used in all fields involving enzymatic reactions, by taking advantage of the selectivity, for example for dosages in the chemical industry, in the medical and biological fields, as well as in the agricultural and food industries.</p> |
