ABSTRACT
Biosensors play an important role in clinical detection, environment monitoring, food analysis, and also in some other elds. The advancement of biomaterials has profound direct impacts on the development of biosensors. On one hand, the application of biorecognition materials determines the function and use of biosensors based on their biological nature. On the other hand, the introduction of intermedia biomaterials impacts on properties and ef ciencies of biosensors because of their effects on biorecognition material immobilization and signal transferring. In this chapter, we have summarized most of the biorecognition materials such as enzymes, microbes, DNA, and antigens-antibodies that have been used in biosensors, and some special biomaterials mentioned as intermedia materials in biosensors have been listed. We described processing techniques to prepare biorecognition materials and intermedia materials and assemble them as functional biosensors.
