Review on CNTFET: Recent Developments in Biosensors for Health Care Applications

Abstract

Abstract: With the increasing use of high-performance component circuits (VLSI) in biosensing, there has been remarkable progress in the field of nanotechnology. The carbon nanotube is basically made of graphite sheets wrapped to form a tubeshaped structure, with a periodic boundary structure that makes a hexagon that never breaks. Carbon nanotube field-effect transistors (CNTFETs) have lower latency and power consumption compared to compatible CMOS devices, so they are considered a viable option to switch CMOS devices to VLSI circuits with very low power. Biomedical sensors have received a lot of attention in the field of health care. CNTFETs have a high potential to drive many technological advances in the industry due to their unique electrical structures of CNTs. In this review, we focus on the use of CNT-based FET (CNTFETs) in biomedical systems. It starts with the introduction of the device and discusses four applications where CNTFETs are used, namely covid-19, hearing aid, cholesterol, and cancer. Finally, we conclude the review with an overview of CNTFET in the medical field. Keywords: Biosensing, Nanomaterial, CNTFET, Covid-19, Hearing aid, Cholesterol, and Cancer
