Transistor Based Biosensors

Transistor-based biosensors offer a revolutionary approach to biomolecule detection, utilizing transistors as the sensing element. This technology holds immense potential for developing highly sensitive, selective, and specific sensors for diverse applications. 

These biosensors typically employ a thin film transistor (TFT) functionalized with a specific biological molecule, like an enzyme, antibody, or DNA probe. When the target analyte (biomolecule or chemical compound) interacts with this biological probe, it triggers a signal that the TFT can detect. 

Transistor-based biosensors Advantages:-
High sensitivity, selectivity, and specificity: Detecting even minute amounts of target analytes with high accuracy. 
Real-time detection: Providing immediate results for rapid analysis. 
Miniaturization: Enabling development of portable and wearable biosensors for on-the-go detection. 

Transistor-based biosensors Applications: 
Medical diagnostics: Detecting glucose, cholesterol, and other biomolecules for disease diagnosis and monitoring. 
Environmental monitoring: Identifying pollutants and contaminants in water and air. 
Food safety: Detecting foodborne pathogens and contaminants. 
Biosecurity: Identifying bioterrorism agents. 

The future of transistor-based biosensors is bright, with ongoing research focused on: 
Improved performance and reliability 
Exploration of new materials 
Development of novel applications 

Overall, transistor-based biosensors represent a transformative technology with immense potential to revolutionize the way we detect and analyze biomolecules across a wide range of applications.
