Molecular-electromechanical system for unamplified detection of trace analytes in biofluids

We present the design, assembly and implementation of a molecular-electromechanical system composed of a tetrahedral DNA nanostructure immobilized on a graphene field-effect transistor for unamplified detection of trace amounts of analytes in biofluids.
