                      monodisperse nanoparticles based on the intrinsic property
                      of gold(I) ions to form aurophilic interactions stabilized
                      by oleylamine and long-chain alkylamine have been widely
                      explored. Due to the low thermodynamic stability of the high
                      aspect ratio nanostructures, their conjugation and assembly
                      into functional nanosystems have not been explored so far.
                      One of the reasons for this is that the surface of the
                      nanostructures is insulated by stabilization compounds,
                      which preserve the integrity of the nanostructures but at
                      the same time form an insulating barrier in electronic and
                      electrochemical systems in contact areas and for the charge
                      transfer reactions. Conjugation of a metalloprotein
                      cytochrome c (Cyt c) with oleylamine-stabilized gold
                      ultrathin nanowires and nanoparticles into a
                      bioelectrochemically active nanoarchitecture is presented
                      here for the first time. Methods of preparing and assembling
                      the ultrathin nanowires and nanoparticles on the thin-film
                      gold electrodes are shown. Thermodynamic and kinetic
                      parameters were obtained for the direct electron transfer
                      reaction of cyt c on these surfaces. Nanowires are
                      responsible for an approximately −20 mV shift in the redox
                      potential of the ferri/ferro-cyt c couple relative to a
                      thin-film gold electrode.},
