Abstract
Official abstract text for this publication.
A reagent layer of a sensor contains as a mediator a quinone compound having a hydrophilic functional group, phenanthrenequinone, and/or a phenanthrenequinone derivative. The quinone compound has a lower redox potential than a conventional mediator, so interfering substances have less effect on detection results with this sensor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A sensor for detecting or quantifying a target substance contained in a liquid sample, comprising: a phenanthrenequinone and a phenanthrenequinone derivative as a mediator; an enzyme dehydrogenating or oxidizing the target substance; and at least a pair of electrodes; wherein the amount of the phenanthrenequinone and the phenanthrenequinone derivative contained in the sensor is 0.05 to 2500 nmol per unit of the enzyme. 2. T…
