<P>PROBLEM TO BE SOLVED: To realize a device for measuring hemoglobin, for measuring a hemoglobin concentration of a sample with high precision, even if the sample is small in size and very small in quantity. <P>SOLUTION: A first electrode (working electrode) 1 and a second electrode (reference electrode) 2 are formed on the surface of a silicon substrate 4 and a reaction vessel 3 contact both the working electrode 1 and the reference electrode 2. The sample is introduced into the reaction vessel 3, and thus continuity between both the electrodes 1, 2 is established through the sample. Oxidation-reduction potential occurs without a voltage or a current externally supplied. The oxidation-reduction potential is measured by a voltmeter 6 and the hemoglobin concentration is calculated by Nernst's equation. Thus, a power source to supply electric power between two electrodes is unnecessary and measurement is done even if the sample is very small in quantity, which achieves a hemoglobin measuring device for measuring the hemoglobin concentration of the sample even if the sample is small in size and very small in quantity. <P>COPYRIGHT: (C)2010,JPO&INPIT |
