The detection target substance measurement method using the enzyme sensor and the enzyme sensor

摘要

PROBLEM TO BE SOLVED: To provide an enzyme sensor by which reliable high sensitivity measurement is possible at low cost, and a detection target substance measuring method using the enzyme sensor.;SOLUTION: In the enzyme sensor 1 which compares activity of an enzyme in electrolyte 11 at a detection target substance non-added state that the detection target substance is not added with activity of the enzyme in the electrolyte 11 at a detection target substance added state that the detection target substance is added to measure concentration of the detection target substance in the electrolyte 11 at the detection target substance added state from a reduction degree of the activity of the enzyme, the concentration of the enzyme in the electrolyte 11 is set to the concentration in which an inclination of a straight line to be obtained when the concentration [U/ml] of the enzyme is considered as a horizontal axis, and a detected value based on detection data by a detection part 10 when a substrate which the enzyme selectively acts is added to the electrolyte 11 at the detection target substance non-added state is considered as a vertical axis becomes a threshold for a predetermined enzyme inclination or more.;COPYRIGHT: (C)2012,JPO&INPIT
