<P>PROBLEM TO BE SOLVED: To perform high-sensitivity and accurate measurement of without making measurement operation complex. <P>SOLUTION: This measuring method of a substance to be inspected using metal fine particles as a labeling substance has a process of collecting metal fine particles on the surface of an acting electrode by utilizing biological interaction, a process of electrochemically oxidizing the metal fine particles collected on the surface of the acting electrode to elute them, in a state where an opposed member having a flat surface is allowed to approach the surface of the acting electrode, and a process of measuring the current value, when the eluate due to the electrochemical oxidation by the acting electrode is reduced electrochemically. <P>COPYRIGHT: (C)2009,JPO&INPIT |
