Sensors play a pivotal role in modern analytical sciences, particularly in the development of high-performance platforms for the detection of biological and chemical analytes. Applications span health care, environmental monitoring, breath diagnostics (breathonics), and industrial safety. Whether detecting biomarkers in body fluids or volatile organic compounds (VOCs) in exhaled breath, target molecules are typically found at trace concentrations, often in complex sample matrices. This necessitates the design of sensing systems that are highly sensitive, selective, and robust under diverse operating conditions. Nanomaterial-based sensor platforms, such as carbon nanotube (CNT)-based field-effect transistors (FETs), emerged as promising candidates, enabling the development of co...
