The electrochemical behavior of ferritin at the polarized water|1,2-dichloroethane (DCE) interface was studied, mainly under acidic conditions. No obvious voltammetric responses were observed under neutral and alkaline conditions where ferritin formed an uncharged nanocage structure. On the other hand, large electrochemical responses were obtained in the positive potential region under acidic conditions where ferritin was disassembled into positively charged subunits. These responses varied slightly with the concentration of the supporting electrolyte in the organic phase and changed drastically with the concentration of ferritin and under repetitive sweeps. In addition, depending on the applied potential and the concentration of ferritin, a white film was formed at the interface. This electrochemical behavior could be attributed to ion transfer and the adsorption/desorption of positively charged ferritin subunits with the interfacial activity accompanied by the facilitated ion transfer of the organic supporting electrolyte anion.

主要在酸性条件下研究了铁蛋白在极化水1,2-二氯乙烷（DCE）界面上的电化学行为。在铁蛋白形成不带电的纳米笼结构的中性和碱性条件下，没有观察到明显的伏安响应。另一方面，在酸性条件下，铁蛋白被分解成带正电的亚基，在正电势区域获得了较大的电化学响应。这些响应随有机相中支持电解质的浓度而略有变化，并且随着铁蛋白的浓度以及在重复扫描下急剧变化。另外，根据施加的电位和铁蛋白的浓度，在界面处形成白色膜。
