Abstract
  • Transduction of biorecognition events into electrical signals through integration of single redox metalloproteins in bioelectronic nanodevices requires both a reliable electrical contact between the biomolecule and the metallic electrode and an efficient overall conduction mechanism. These conditions have been met in the hybrid system obtained by linking gold nanoparticles on top of Azurin proteins, in turn assembled on gold surfaces. Such an assembling strategy, combined with a conductive atomic force microscopy investigation, has allowed us to put into evidence an unprecedented matching between current and topography features and to attribute the intramolecular charge transport to a non-resonant tunnelling mechanism.
