A highly sensitive glucose detection method was developed using functionalized carbon nanotube buckypaper as a free standing electrode in an electrochemical biosensor. Glucose oxidase was immobilized onto various buckypaper samples in order to oxidize glucose resulting in a measureable current/voltage signal output of the biosensor. Cyclic voltammetry (CV) and amperometry were utilized to determine the sensitivity of these buckypaper electrodes. Sensors of three different types of buckypaper were prepared and compared. These modified buckypaper electrode-based sensors showed much higher sensitivity to glucose compared to other electrochemical glucose sensors.
采用功能化碳纳米管巴基纸作为电化学生物传感器中的独立电极，开发了一种高灵敏度的葡萄糖检测方法。将葡萄糖氧化酶固定在各种巴基纸样品上，以氧化葡萄糖，从而测量生物传感器的可测量电流/电压信号输出。利用循环伏安法（CV）和安培法来确定这些巴基纸电极的灵敏度。制备并比较了三种不同类型的巴基纸传感器。与其他电化学葡萄糖传感器相比，基于这些改性巴基纸电极的传感器对葡萄糖具有更高的灵敏度。
