The present invention provides a sensor for detecting or quantifying a target substance contained in a liquid sample. The sensor comprises a quinone compound that accepts electrons released as a result of dehydrogenation or oxidization of the target substance by the enzyme; and at least a pair of electrodes, wherein the quinone compound contains a quinone and a substituent, wherein the substituent is hydrophilic. The quinone compound has a lower redox potential than conventional substances, so interfering substances have less effect on detection results with this sensor, particularly the redox potential of the quinone compound measured using a silver/silver chloride (saturated potassium chloride) electrode as a reference electrode is more negative than the oxidization potential of ascorbic acid.
本发明提供了一种用于检测或量化液体样品中所含目标物质的传感器。该传感器由醌化合物和至少一对电极组成,其中醌化合物含有醌和取代基,取代基为亲水性。醌化合物的氧化还原电位低于传统物质,因此干扰物质对该传感器检测结果的影响较小,特别是使用银/氯化银(饱和氯化钾)电极作为参比电极测量的醌化合物的氧化还原电位比抗坏血酸的氧化电位更负。
