About the Book

Field-effect transistors (FETs) have been investigated widely as biosensors for pathogen detection, with advantages such as label-free and real-time detection capabilities. These biosensors utilize the changes in electrical properties, such as current and voltage, induced by the presence of pathogens on the channel surface of the transistor. The devices have a high level of sensitivity, a remarkable capacity for miniaturization, a molecular minimum limit of detection (LoD), and seamless integration with semiconductor technology. Infectious diseases continue to be a challenging field that necessitates increased precision in detection and integration in order to achieve accurate diagnosis at the point of care (PoC). In this title, we invited several expert scientific researchers to share their experience in this field. This book is dedicated to focusing on the application of FETs as biosensors, for rapid and real-time detection of pathogens that affect the human life. The lack of commercially available efficient devices that can be deployed for this task hampered efforts to curb the recent global spread of the SARS-CoV-19 virus. The book is an attempt to keep the interested audience up to date on this subject.
