✦ Synopsis

Abatraet4raphtuz substrates (plates and carbon fibre 7 pm m diameter) have been used and characterlzed m order to obtain glucose senWve electrodes Preparation of such electrodes before enzymatic sensitization and after cleamng involves a specific electrochermcal prttreatment of oxidation at + 2 3 V/ see Further covalent unmobrhzation of glucose oxldase proceeds through a grafting between surface carboxyl group and a carbodumide reagent Performances of enzymatic electrodes such as thar stability up to two months make them well smted for further apphcatlon m the biomedical field Key words carbon fibre, graphite,
