Electrical conductivity of cytochrome c anhydrous film

Abstract Electrical conducitivities of both ferricytochrome c and ferrocytochrome c anhydrous films were measured at physiological temperatures. A film-casting method was applied to prepare the films. Rather low values of resistivities (55°C) of 6.5 × 10 10 Ω cm for ferrocytochrome c in comparison with the previously reported value of 10 11 Ω cm (127°C) were obtained. Apparent activation energies for the above conductivities, 0.6 eV, were the same in both samples.
