ABSTRACT:
Methods for sensing and building sensors provide for adding nanotubes to a sensor to improve characteristics such as the Q-factor associated with the sensor. Mass loading and damping characteristics of micromachined quartz crystal resonators on which a thin film of debundled single-walled carbon nanotube (SWNT) has been deposited are disclosed. An absolute mass sensitivity of ˜100 fg was experimentally measured by monitoring the continuous desorption of gases from SWNT surfaces in a vacuum ambient.
