化学和生物传感器已经吸引了极大的兴趣,由于其在医疗保健,食品质量监测,环境监测等应用的重要性。碳纳米管(CNT)为基础的场效应晶体管(FET)是一种新型的传感器件配置,是非常有前途的,因为他们的潜力,以推动许多技术进步,在这一领域由于非凡的电性能的碳纳米管。本文综述了碳纳米管基场效应晶体管(CNTFFET)在化学和生物传感器中的应用。首先介绍了碳纳米管的性质,以及碳纳米管的表面功能化。然后,CNT FET的配置和传感机制进行了介绍。其次,综述了基于碳纳米管的化学传感器和生物传感器的研究进展。最后,我们总结了目前的应用现状和基于碳纳米管场效应晶体管的化学和生物传感器所面临的挑战。
Chemical and biological sensors have attracted great interest due to their importance in applications of healthcare, food quality monitoring, environmental monitoring, etc. Carbon nanotube (CNT)-based field-effect transistors (FETs) are novel sensing device configurations and are very promising for their potential to drive many technological advancements in this field due to the extraordinary electrical properties of CNTs. This review focuses on the implementation of CNT-based FETs (CNTFETs) in chemical and biological sensors. It begins with the introduction of properties, and surface functionalization of CNTs for sensing. Then, configurations and sensing mechanisms for CNT FETs are introduced. Next, recent progresses of CNTFET-based chemical sensors, and biological sensors are summarized. Finally, we end the review with an overview about the current application status and the remaining challenges for the CNTFET-based chemical and biological sensors.
