To know if the oil/water (O/W) interface can be a model system of biomembrane, electron transfer reactions occurring at a self-assembled monolayer (SAM) modified electrode (which seems to be more analogous to biomembrane systems) have been compared with those occurring at the O/W interface.Using electrochemical techniques such as cyclic voltammetry, it has been found that the Galvani potential difference across the SAM/solution interface should play an important role in the electron transfer occurring therein, in a similar manner as the electron transfer at the O/W interface. However, we can observe a biomimetic electron transfer for cytochrome c at the SAM/solution interface, though no such electron transfer occurs at the O/W interface.
