Biosensor for determining concentration of glycated hemoglobin by means of potentiometry

摘要

bio-sensors for measuring glycated hemoglobin according to the present invention, the reference electrode; And home on the whole, including the specific binding sites available in the glycated hemoglobin and the molecules are aligned with a redox electrode potential variation is changed by binding glycated hemoglobin without the supply of voltage and current from an external measurement unit; By a potential difference method (Potentiometry) for measuring the potential difference variations between the electrode and the reference electrode, the potential difference measuring circuit or a potential difference titrator; And optionally converted to a jeonwichayi value or amount or concentration of glycated hemoglobin in this sample between the mutant and reference electrodes and a display unit for displaying. Biosensor for measuring glycated hemoglobin according to the present invention is effective to quickly and accurately measure the concentration of glycated hemoglobin in the sample, the density of the two materials at the same time, without going through a separation step in the concentration of hemoglobin and glycated hemoglobin, the measurement of glycated hemoglobin can be measured by the ratio obtained. ;
