免疫传感器是生物传感器家族中的一个新成员，它有两个基本组成部分：敏感源（ 抗体或抗原） 和信号转换器．其中常见的信号转换器有电化学信号转换器，质量信号转换器，热量信号转换器和光学信号转换器．本文将从生物传感器的基本结构入手，集中讨论电化学信号转换器在免疫传感器中的应用．
Immunosensors are a new member of the biosensor family that has two basic components: a sensitive source (antibody or antigen) and a signal converter. Among the common signal converters are electrochemical signal converters, mass signal converters, thermal signal converters and optical signal converters. This article will start with the basic structure of biosensors, focusing on the electrochemical signal converter in the application of immune sensors.
