Biosensor for direct determination of glucose and lactate in undiluted biological fluids.
This paper describes the implementation of a bienzyme sensor for the direct determination of glucose and lactate in undiluted biological samples. The biosensor exploits the competitive action versus the substrate itself by two different enzymes immobilized into a sandwich of two different membranes. In this way the quantity of substrate reaching the indicating electrode is reduced and this determines an extension of the linearity range.
