Abstract:

The field-effect transistor (FET) biosensor is a type of sensor based on the principle of detecting biomolecules or biomarkers. Due to the signal amplification characteristics of its electric field effect, it enables the detection of biomolecular interactions at extremely low concentrations, further enabling biomolecular recognition. In the field of nucleic acid detection, this approach offers the unique advantage of eliminating the need for nucleic acid amplification, resulting in shorter detection times. Additionally, FET biosensors also excel in nucleic acid detection performance, portability, and cost-effectiveness. Overall, FET biosensors can achieve ultra-rapid and ultra-sensitive targeted identification of viral genes. Combined with microfluidic technology, nanomaterials, or flexible electronic materials, they hold significant promise for application in food safety, clinical diagnosis, genotyping, biosafety, and other fields. To facilitate the better application of FET sensors in biological detection, this review summarized the current applications of FET biosensors in nucleic acid detection and provided a classification and discussion based on the biological recognition layer, aiming to offer insights for future research in this area.
