We report the fabrication of suspended carbon nanotube field effect transistors (CNT FETs) designed for biological sensing applications. We compare the electrical properties of our suspended CNT FET design to standard surface based CNT FETs. In particular, we show a reduction in environmental noise, suggesting that the new sensor design is a promising candidate for low-noise sensing applications.
