一、引言 生物传感器是将生物体的优异反应特性引入电化学计量中的一种装置,由两个部分组成,一部分是敏感膜,它具有高灵敏的选择性,用来鉴别被测物,另一部分是测量部分,是一种检测敏感膜上发生的电信号的装置。 I. INTRODUCTION Biosensor is a kind of device which introduces the excellent reaction characteristics of organism into electrochemical metrology. It consists of two parts, one is sensitive membrane, which has high sensitivity and selectivity to distinguish the measured object from the other Part of the measuring part is a device that detects electrical signals that occur on sensitive membranes.
