抄録

We confirmed the specific detection of immunoglobulin E (IgE) using an aptamer-immobilized reduced graphene oxide (rGO) field effect transistor (FET). The detection limit and dynamic range were estimated to be 8.1 ng/ml and 10 4 , respectively. These characteristics are comparable with these of current fluorescent markers. Although the mobility of rGO-FET was around 6 cm 2 V −1 s −1 , which is two to three orders lower than that of mechanically exfoliated pristine graphene FET, its sensitivity to IgE was only one order lower than that of pristine graphene FET.
