Abstract
As the conventional simple bio-sensors for measuring the particular component in living bodies, there are those in which a change in dye caused by enzyme reaction is detected optically, but such bio-sensors had a problem that precision is low owing to disturbance of the color of liquid samples. With bio-sensors using an enzyme electrode, the precision was high, but operation of measurement was troublesome. The present invention made it possible to detect the concentration of the particular component electromechanically with rapidity, simplicity and high precision by merely putting a porous substrate containing at least enzyme on the electrode system and impregnating the body with a liquid sample.
