2 results about "Graphene field effect transistors" patented technology

Bifunctional graphene dielectrophoresis (DEP)-graphene field effect transistor (GFET) devices are provided. Aspects of the devices include: a graphene dielectrophoresis (DEP) component and a graphene field effect transistor (GFET) component, wherein the graphene DEP and GFET components are independently operable. Also provided are methods of evaluating a sample for the presence of an analyte, e.g., by introducing the sample into a bifunctional graphene dielectrophoresis (DEP)-graphene field effect transistor (GFET) device and obtaining a result from the device providing information as to whether the analyte is present in the sample. In addition, kits comprising the devices or systems described herein are provided. The devises, systems, methods and kits find use in a variety of different applications, including research and diagnostic applications.

Provided are electronic biosensors based on graphene field effect transistors that utilize engineered hairpin probe DNA that allows for target recycling and hybridization chain reactions.
