Nanoresonators in Sensors and Molecular Transportation: An Introduction to the Possibilities of Carbon Nanotubes and Graphene Sheets

Recent studies in the growing field of nanotechnology have been oriented toward the development of nanomechanical resonator systems. The ultrahigh frequency of nanoresonators facilitates a wide range of new applications such as ultrahigh-frequency-sensitive sensors, molecular transportation, high-frequency signal processing, biological imaging, quantum measurement, and radio-frequency communications. In this article, the applications of nanoresonators made of carbon nanotubes (CNTs) and graphene in sensors and molecular transportation are reviewed. Studies on the use of nanoresonators for the detection of atoms/molecules based on vibration and wave propagation analyses are outlined.
