作者用微电子平面工艺制备了多种平面电极阵列,研究了它们的电化学特性.实验证明:微电极阵列能极大地提高响应电流并保持单一微电极的全部优点,即尺寸越小,响应时间越短,电流密度越大,能使用的电位扫描述率越高.并又共价键合葡萄糖氧化酶,研制成功具有良好性能的微型化葡萄糖传感器,它的响应电流比现有报导的单一微电极的葡萄糖传感器大十多倍. The authors fabricated a variety of planar electrode arrays using microelectronics planar technology and studied their electrochemical properties.The experiments show that the microelectrode array can greatly improve the response current and maintain all the advantages of a single microelectrode, namely, the smaller the size, the smaller the response time The shorter the current density is, the higher the potential sweep potential is and the more covalently bind glucose oxidase to develop a miniaturized glucose sensor with good performance. The response current is lower than that of the single micro-sensor The electrode glucose sensor more than ten times.
