Abstract
Biosensor research has been addressed as an interested field recently. Within different kinds of developed biosensing technologies, field-effect transistor (FET) based biosensors stand out due to their attractive features, such as ultra-sensitivity detection, massproduction capability, and low-cost manufacturing. To promote understandings of the FET based biosensing technology, in this review, its sensing mechanism is introduced, as well as major FET-based biosensing devices: ion sensitive field-effect transistor (ISFET), silicon nanowire, organic FET, graphene FET, and compound-semiconductor FET. In addition to FET-based biosensing devices, clinical applications, such as cardiovascular diseases (CVDs), cancers, diabetes, HIV, and DNA sequence, are also reviewed. In the end, several critical challenges of FET-based biosensing technology are discussed to envision next steps in healthcare technologies. ? The Author(s) 2018. Published by ECS.
