Towards Protein Field-Effect Transistors: Report and Model of a Prototype

A protein field‐effect transistor (Pro‐FET) based on the blue‐copper protein azurins (see Figure) and operating at room temperature and ambient pressure is demonstrated. The transfer characteristics of the Pro‐FET exhibit a pronounced resonance due to the switch from behaving as a n‐metal oxide semi...

Zusammenfassung:A protein field‐effect transistor (Pro‐FET) based on the blue‐copper protein azurins (see Figure) and operating at room temperature and ambient pressure is demonstrated. The transfer characteristics of the Pro‐FET exhibit a pronounced resonance due to the switch from behaving as a n‐metal oxide semiconductor FET (n‐MOSFET) to a p‐MOSFET. Carrier transport through the device is explained in terms of an equilibrium between the two possible oxidation states of the redox site (Cu1+ and Cu2+).
