Fast & Miniaturized Biosensor for Liver Disease Detection
Field-Effect Transistor Device for the Detection of Dissolved Ammonia in Plasma
Tags: IIT Delhi, India, Healthcare & Lifesciences
A highly responsive field-effect transistor (FET) biosensor based on tungsten trioxide (WO₃) thin film has been developed for real-time detection of ammonia in human plasma. This miniaturized and biocompatible sensor offers high sensitivity, fast response, and requires only 2 µl of sample, making it more efficient than conventional methods. Elevated ammonia levels serve as a prognostic marker for liver disorders, enabling early diagnosis and monitoring. Applications include healthcare industries for point-of-care testing and chronic liver disease management. A functional prototype has been fabricated and validated in a laboratory environment.
