Exploring field effect transistor sensing devices in agricultural breeding environment: application prospects

The advancement of biosensing devices based on field effect transistor (FET) has been rapid, largely due to the simplicity of their operational mechanism, rapid response, ease of miniaturization, and integration. The preparation of field effect transistors using inorganic nanomaterials as channel materials has been extensively employed in biosensing applications, including assessing food quality and safety, environmental monitoring, and diagnosing biological diseases. The detection of disease-causing microorganisms, antibiotics, heavy metals, and harmful gases in modern agricultural breeding environments also necessitates the utilization of sensors that are able to achieving label-free, miniaturized, rapid, and specific detection. Biosensing devices based on field effect transistors are able to rapidly and specifically detect, meeting the needs of modern agricultural breeding environments for low-cost, accurate, miniaturized, and portable devices.
