Abstract

Abstract:

The combination of nanomaterials and biosensing elements to selectively recognize biological molecules promotes the development of nanobiosensors. Nanomaterial-based field effect transistor biosensors are one of newly developed biosensing technologies. Compared with the conventional detection technologies, they offer several important advantages including high sensitivity and selectivity, rapid analysis, label-free detection, easy operation and so on. This review summarizes the working principle and fabrication of field effect transistor biosensors based on graphene, silicon nanowires and carbon nanotubes and their applications in medicine detection.

Key words: Biosensor, Nanomaterial, Field effect transistor, Medical detection, Application
