Amino acid biosensor, Fisher ratio biosensor, and health information management system

摘要

To provide a biosensor that can be measured by the electrode plate system of a single total concentration of multiple amino acids. Amino acid biosensor for measuring the total concentration of amino acids in a particular multiple (200), an enzyme as a substrate selectively to particular amino acids in the plurality of poles and measuring a constituent factor mediator (202) and a counter electrode and (203), and the enzyme has a substrate affinity to each of specific amino acids of the plurality, the enzyme produces a reaction product by reaction with a substrate amino acids that particular mediator The carry electrons between the measuring electrode with the reaction product when measuring the concentrations of the amino acids, the applied voltage and measuring the time between the counter electrode and the measuring electrode of the amino acid biosensor, applying for each particular amino acid multiple In the calibration curve showing the relationship between current value and voltage, and a voltage applied to the distribution of the current at the same applied voltage for each amino acid is such that within a predetermined range.
