Can the oil/water interface be a model system of biomembrne? -Similarities and Differences as the reaction field of electron transfer-

为了了解油/水界面是否可以作为生物膜的模型体系，在自组装单分子层（SAM）修饰电极上进行电子传递反应（这似乎更类似于生物膜系统）已经与发生在O/W界面的那些进行了比较。使用电化学技术如循环伏安法，已经发现，SAM/溶液界面上的伽伐尼电位差在其中发生的电子转移中起重要作用，其方式与O/W界面处的电子转移类似。然而，我们可以观察到细胞色素c在SAM/溶液界面的仿生电子转移，虽然没有这样的电子转移发生在O/W界面。

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.
