Charge Plasma TFET-Based Label-Free Biosensor for Healthcare Application

Because of the capability of biosensing technology in the medical field, environmental monitoring, and security applications, field-effect transistor-based biosensors are seeing accelerated growth in popularity. Recently, the use of silicon nanowires for biosensing has made it possible to miniaturize devices and improve sensing performance. However, reliability problems resulting from the difficulties of regulating the production parameters at nanoscale impede the sensing performance with the introduction of nanoscale BioFETs. Field-effect transistors have recently used the junctionless (JL) technique to get over manufacturing challenges where current is controlled by bulk conduction. JL transistors’ lack of steeper doping profiles simplifies manufacturing challenges and lowers device variability. Next-generation biosensors must be capable of detecting target molecules with increased sensitivity, rapid response, and reduced detection limit. However, advanced research is required to determine the possibility of junctionless transistors like biosensors.
