生物传感器的基本结构由两部分组成。一部分是选择性识别被测物质的感受器,为生物敏感元件;另一部分是能量转换器,即将能量从一种形式转换成另一种形式的传感元件。前者文献介绍颇多,故对后者做一概述。 七十年代的生物传感器为电化学装置,其转换器为电极。包括离子选择性电极、气敏电极(二氧化碳和氨电极)及氧电极。离子选择性电极有一敏感膜,电极借敏感膜对某一种离子产生选择性响应,
The basic structure of biosensors consists of two parts. One is the sensor that selectively recognizes the substance under test, and the other is the energy converter, which converts the energy from one form to another. The former a lot of literature, so make an overview of the latter. Seventies biosensors for electrochemical devices, the converter for the electrode. Including ion-selective electrode, gas sensor (carbon dioxide and ammonia electrode) and oxygen electrode. Ion selective electrode has a sensitive membrane, the electrode by the sensitive membrane of a selective ion selective response,
