Abstract

Abstract : Graphene Biosensors In article 2106666, Xiaoyan Zhang, Grégory F. Schneider, Wangyang Fu, and co‐workers demonstrate graphene biosensors operating at ultrahigh frequencies, where the conductivity of high‐salt solutions and thus the ionic screening is fully cancelled. Dielectric‐modulated detection of the binding of streptavidin molecules to biotin molecules that are noncovalently anchored on the graphene surface is demonstrated using the developed graphene biosensors.
