These days the enzymatic analytics and physical measuring methods are of increasing significance. Theoretically this combination should solve all interference problems and improve the selectivity of analysis. However, this fails sometimes, e.g. measurements in complex solutions still raise a lot of problems for the analyst.We have developed a biosensor designed for use by the food producing industry that enables us to examine turbid, heterogeneous, coloured and similar liquids. This sensor solves some of the problems mentioned above. The sensor is unique since its measuring head works without a membrane. In addition an electron-transfer-mediator and immobilized enzymes in the paste of the measuring head are used.
