A bioelectrochemical-sensor device was designed according to the principles of galvanic cell reaction. Modified bioelectrochemically, the device was used to measure the current of samples from benign and malignant tumor tissues. Statistical analysis and clinical test showed that the current values (426 microA) of the malignant tissue were higher than those (216 microA) of the benign tissue. The sensitivity and specificity were 95% and 90% respectively. This method provided important information about benignancy or malignancy of the tumor and its involvement and metastasis.
一种生物电化学传感器设备是根据原电池反应原理设计的。该设备经过生物电化学修饰后，用于测量来自良性和恶性肿瘤组织样本的电流。统计分析和临床试验表明，恶性组织的电流值（426微安）高于良性组织的电流值（216微安）。灵敏度和特异性分别为95%和90%。该方法为肿瘤的良性或恶性及其累及和转移提供了重要信息。
