Application of sensor structures based on a photoelectric transducer to determine the activity of aspartate and alanine aminotransferases in blood plasma.

The successful application of a recombination sensor for the real-time detection of transaminasethe detection of transaminase activities (/) in the blood plasma of rats has been demonstrated. The parameter directly measured in real time is the photocurrent through the structure with buried silicon barrier when light with high absorption coefficient is used. Detection is realized as a result of specific chemical reactions catalyzed byandenzymes (-ketoglutarate + aspartate and-ketoglutarate + alanine).
