Hybrid three terminal devices based on modified DNA bases and metalloproteins

The key challenge of current research in nanoelectronics is the realization of biomolecular devices. The use of DNA bases and electrontransfer proteins, such as blue copper protein azurin (Az), is particularly attractive because of their natural self assembly capability. We will present our results concerning the fabrication, characterization and modeling of hybrid three-terminal devices based on deoxiguanosines (modified DNA bases) and azurins. These molecular devices exhibit novel operational functions, thus opening the way to the implementation of a new generation of logic architectures.
