Field-Effect Transistor Based Biosensing: Development and Applications

Dear Colleagues,

There is great interest in 1D and 2D nanomaterials for biological sensors, and this interest has become even stronger in the current pandemic context with no availability of specific drugs or vaccines to stop the spread of the virus. Likewise, early detection via biological sensors could help to improve the management and containment of the outbreak. The integration of 1D and 2D nanomaterials into electrical devices offers substantial advantages for the detection of biological species and has significant advantages over conventional optical bio-detection methods. The integration of electronics with biology into a common platform suitable for electronic control and biological sensing provides a great potential for biosensing applications.

Among various sensing methods currently available, field-effect transistor (FET)-based biosensors are advantageous due to their attractive features, such as ultra-sensitivity detection and low-cost manufacturing. A plethora of materials and devices have been developed to promote the understanding of FET-based biosensing technology, including ion-sensitive field-effect transistors (ISFETs), CNT based FETs, thin-film transistors, silicon nanowires, 2D materials, organic FETs, graphene FETs, and compound-semiconductor FETs. These materials/devices have been used for a variety of clinical applications such as detection of cardiovascular diseases (CVDs), COVID-19, proteins, enzymatic reactions, glucose, stress hormones (e.g., cortisol), cancers, HIV, and DNA sequences.

We are pleased to invite you to contribute to this Special Issue on “Field-Effect Transistor Based Biosensing: Development and Applications”. This Special Issue will highlight recent advancements in the development of different advanced materials and FET devices for potential application in clinical diagnosis, point-of-care testing, and on-site detection. We encourage researchers to share their theoretical and experimental studies on a variety of topics in biosensors, including fundamental principles, synthesis of advanced and novel materials, and micro/nanomanufacturing techniques targeting the development of ultrasensitive biosensors for the above-mentioned applications.
