摘要: The present invention discloses a protein transistor device, wherein an antibody molecule (antibody-antigen) is bonded to at least two gold nanoparticles in a high reproducible self-assembly way to form molecular junctions, and wherein the two gold nanoparticles are respectively joined to a drain and a source. The protein transistor device can be controlled to regulate current via applying a bias to the gate. The conformational change of the protein molecule will cause the variation of the charge transport characteristics of the protein transistor device. The protein transistor device can be further controlled by different optical fields via conjugating a quantum dot to the molecular junctions. Therefore, the present invention has diversified applications.
