This paper demonstrates a novel way of using a single type of high electron mobility transistor (HEMT) device for detecting two kinds of biomolecules (Photosystem I and recombinant human monokine induced by interferon gamma, MIG). MIG was successfully detected in 150 mM concentration of phosphate buffer solution (PBS). Floating gate configuration used for biomolecule detection eliminates the need of external gate voltage and represents purely the effect of biomolecules immobilization and binding events on the gate surface.
