Detection of Exosomes Using Liquid-Gated Graphene Field Effect Transistor Biosensors
2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)(2021)
Abstract
In this paper, liquid-gated graphene field effect transistor (LG-GFET) biosensors are demonstrated for exosomes sensing. Since the exosome is negative charged and thus served as n-type doping effect to graphene, the conductivity of the LG-GFET will varied loading with different exosome concentration. Therefore, exosomes concentration can be distinguished by detecting drain-source current (Ids...
