摘要: This review provides a critical overview of current developments on nanoelectronic biochemical sensors based graphene. Composed single layer conjugated carbon atoms, graphene has outstanding high carrier mobility and low intrinsic electrical noise, but chemically inert surface. Surface functionalization is therefore crucial to unravel sensitivity selectivity for the detection targeted analytes. To achieve optimal performance transistors sensing, tuning surface properties via passivation highlighted, as well its operation by utilizing multifrequency ambipolar configuration frequency measurement scheme overcome Debye screening noise highly sensitive detection. Potential applications prospectives ultrasensitive electronic ranging from environmental monitoring food safety, healthcare medical diagnosis, life science research, are presented well.
