Research progress of graphene field effect transistor biosensor in medical detections / 国际检验医学杂志

ABSTRACT

In recent years, more and more attention has been paid to the integration of nano-material graphene and field effect transistor to construct biosensor for detecting biomolecules.This is mainly due to the following advantages of graphene field effect transistor inculding high sensitivity and specificity, rapid analysis, label-free detection, cheap price, miniaturization and integration.This review summarizes the structure and working principle of graphene field effect transistor biosensor, the preparation and functionalization of graphene, and the application of graphene field effect transistor in medical detections.
