A field effect transistor modified with reduced graphene oxide for immunodetection of Ebola virus

The authors describe a field effect transistor (FET) based immunoassay for the detection of inactivated ebola virus (EBOV). An equine antibody against the EBOV glycoprotein was immobilized on the surface of the FET that was previously modified with reduced graphene oxide (RGO). The antibody against EBOV was immobilized on the modified FET, and the response to EBOV was measured as a function of the shift of Dirac voltage. The method can detect...
