A thorough investigation into the development and performance assessment of biosensors that utilize Tunnel Field Effect Transistors (TFETs), showcasing a departure from conventional bio-sensing approaches is carried out. The unique properties TFETs leverage quantum tunneling effects to enable precise efficient detection biomolecules. This review examines impact various device schematic modifications on sensitivity TFET biosensors. analysis focuses methodologies aimed at improving levels, exploring models scholarly literature, assessing shifts in simulated parameters. Such as ON current (ION), Subthreshold Swing (SS), OFF (IOFF), ON-OFF ratio (ION/IOFF), threshold voltage (Vth), sensitivity, selectivity. Among different architectures reported work, Heterojunction Tunneling Transistor (HJ-TFET)-based offer significant advancements biosensing technology due their ability control rates through versatile bandgap materials. Vertical (VTFET) also demonstrate promising potential for label-free specific biomolecule detection, leveraging vertical enhanced electrostatic scalability. Incorporating negative capacitance ferroelectric materials further improves VTFET performance, with ultra-low subthreshold swing high sensitivity. Through exploration latest applications, we illustrate how these nano-enabled gateways health are opening up new possibilities rapid, on-site medical diagnostics, ultimately bringing cutting-edge healthcare solutions. By drawing comparisons established methods, TFET-based show immense promise transforming diagnostics point-of-care offering which crucial monitoring fields such environmental monitoring, food safety.
