摘要
介绍了酶生物传感器的原理、特性及其分类;阐述了第一代传感器获得电信号的途径;引入电子传递介体后的第二代传感器的灵敏性和准确性得到提高;实现第三代传感器的酶在电极上固定的方法和材料。对基于直接电子传递的第三代生物传感器的研究现状进行了评述。最后,展望了生物传感器的发展方向。
The principle,character and classification of enzyme biosensor are introduced.The ways to achieve electric signal of the first generation biosensor,the superiorities of the second generation biosensor with medium and the methods and materials to fixate enzyme of the third generation enzyme biosensor are expounded.The present conditions of the third generation enzyme biosensor are commented on.Finally,the progressive directions of biosensor have also been prospected.
