A potentiometric biosensor for rapid on-site disease diagnostics
文摘

A potentiometric biosensor is developed for direct serological diagnosis of Bovine Respiratory Disease (BRD).

The sensor is based on extended-gate field-effect transistors.

A major pathogen of BRD, Bovine Herpes Virus-1 (BHV-1), is used as a model system.

The sensor performance is equivalent to Surface Plasmon Resonance (SPR) and ELISA.

The FET sensor is significantly faster than ELISA (<10 min).
