ABSTRACT:
Described is an amperometric biosensor in thick film technology for the detection an/or determination of substances undergoing enzyme catalyzed reactions, especially glucose or lactate, comprising an inert carrier material, at least one transducer layer exhibiting a specific electrical conductivity χ>104Ω-1cm-1, and at least one bioactive layer with diffusion barrier function containing at least one enzyme specifically reacting with said substance to be measured, said bioactive layer exhibiting a specific electrical conductivity χ<1 Ω-1cm-1and said bioactive layer further effectively hinders other electroactive substances to reach the transducer layer within the time of measurement.
