Herein, we feature our recent efforts toward the development and application of nanoelectrochemistry at liquid/liquid interfaces, which are also known as interfaces between two immiscible electrolyte solutions (ITIES). Nanopipets, nanopores, and nanoemulsions are developed to create the nanoscale ITIES for the quantitative electrochemical measurement of ion transfer, electron transfer, and molecular transport across the interface. The nanoscale ITIES serves as an electrochemical nanosensor to enable the selective detection of various ions and molecules as well as high-resolution chemical imaging based on scanning electrochemical microscopy. The powerful nanoelectroanalytical methods will be useful for biological and material applications as illustrated by studies of solid-state nanopores, nuclear pore complexes, living bacteria, and advanced nanoemulsions. These studies provide unprecedented insights into the chemical reactivity of important biological and material systems even at the single nanostructure level.
在此，我们介绍了我们最近在液/液界面（也称为两种不混溶电解质溶液之间的界面，即ITIES）开发和应用纳米电化学方面所做的努力。开发了纳米吸管、纳米孔和纳米乳液，以创建用于定量电化学测量离子转移、电子转移和分子跨界面传输的纳米级ITIES。纳米级ITIES用作电化学纳米传感器，能够选择性检测各种离子和分子，并基于扫描电化学显微镜进行高分辨率化学成像。如对固态纳米孔、核孔复合体、活细菌和先进纳米乳液的研究所表明的，这些强大的纳米电分析方法将对生物和材料应用有用。这些研究甚至在单个纳米结构水平上为重要生物和材料系统的化学反应性提供了前所未有的见解。
